Whether you’re looking to improve the stability of your formulations, enhance the

efficiency of your production processes, or develop more environmentally friendly

products, understanding the capabilities and applications of organo bentonite is

essential. This comprehensive guide explores everything you need to know about this

versatile material, from its fundamental properties to its wide-ranging industrial

applications and future development trends.

What is Organobentonite?

Organo clay is an organically modified clay mineral derived from natural bentonite

through a process of surface modification with organic compounds. At its core,

organophilic clay is created by replacing the inorganic exchangeable cations (typically

Na+, Ca2+, or Mg2+) present in natural montmorillonite (the primary mineral

component of bentonite) with organic cations, most commonly quaternary ammonium

compounds or polymers.

The chemical structure of organobentonite consists of nanometer-thick aluminosilicate

layers with organic molecules intercalated between them. This unique structure

fundamentally transforms the properties of the original bentonite clay, converting it

from a hydrophilic (water-loving) material to an organophilic (organic-loving) one. The organic modification significantly alters the surface properties, expanding the interlayer spacing and creating a material with enhanced affinity for organic compounds.

Unlike conventional bentonite, which disperses readily in water but poorly in organic systems, organobentonite exhibits excellent dispersibility in organic media such as solvents, resins, and oils. This fundamental difference stems from the organicmodification process, which shields the hydrophilic silicate surfaces with hydrophobic

organic groups, effectively reversing the natural clay’s polarity.

The preparation of organoclays typically involves several key steps:

1. Purification of raw bentonite to remove impurities and concentrate the

montmorillonite content

1. Dispersion of the purified bentonite in water to create a stable suspension
2. Addition of organic modifiers (quaternary ammonium salts, polymers, or other

organic compounds)

1. Ion exchange reaction between the inorganic cations in the clay and the organic

cations

1. Filtration, washing, and drying of the modified clay
2. Grinding and classification to achieve the desired particle size distribution

The degree of organic modification and the specific organic compounds used can be tailored to meet the requirements of different applications, resulting in a wide range of organobentonite products with varying properties and performance characteristics.

Properties and Characteristics of Organobentonite

The unique combination of inorganic and organic components in organic bentonite clay results in a material with exceptional properties that make it highly valuable across multiple industries. Understanding these properties is crucial for selecting the right organic bentonite product for specific applications.

Physical Properties

Organobentonite typically appears as a fine, off-white to light tan powder with a specific

gravity ranging from 1.7 to 1.8. The particle size distribution can be controlled during

manufacturing, but typically ranges from 2 to 75 microns, with a median particle size of

approximately 6-8 microns. This fine particle size contributes to its high specific surface

area, which typically ranges from 300 to 800 m²/g, providing extensive surface area for

interactions with surrounding media.

One of the most significant physical changes resulting from organic modification is the

increase in the interlayer spacing of the clay. While natural montmorillonite has an

interlayer spacing of approximately 1.2-1.4 nm, organobentonite can exhibit expanded

spacings of 1.8-3.5 nm, depending on the size and arrangement of the intercalated

organic molecules. This expanded structure facilitates the interaction with organic

compounds and contributes to its rheological properties.Chemical Properties

The cation exchange capacity (CEC) of rheological additive bentonite, typically ranging from 70 to 120

meq/100g, indicates its ability to exchange cations and is a measure of the degree of

potential organic modification. The organic content, which can range from 20% to 40%

by weight, reflects the amount of organic modifier incorporated into the clay structure.

The surface chemistry of organobentonite is dominated by the organic groups

introduced during modification, which determine its compatibility with different media.

Depending on the specific organic modifier used, the surface can exhibit varying degrees

of hydrophobicity and organophilicity, allowing for customization to suit different

application requirements.

Rheological Properties

Perhaps the most valuable characteristic of organobentonite is its exceptional

rheological properties. When properly dispersed in compatible systems,

rheology modifiers forms a three-dimensional network structure that imparts thixotropic properties to the system. This means that the material exhibits high viscosity under

static conditions but flows more readily when subjected to shear forces—a property that is particularly valuable in coatings, greases, and other industrial formulations.

The thickening effect of organoclays is concentration-dependent and can be

precisely controlled by adjusting the dosage. Typically, concentrations of 0.5% to 5% by weight are sufficient to achieve significant rheological modification in most systems.

The thickening mechanism involves the formation of a “house of cards” structure, where the edges of the clay platelets interact with each other through the organic modifiers,

creating a network that restricts flow.

Adsorption Properties

The organic modification of bentonite significantly enhances its adsorption capabilities for organic compounds. The hydrophobic nature of the modified surfaces makes organobentonite an excellent adsorbent for oils, solvents, and various organic pollutants.

Adsorption capacities can range from 50 to 300 mg/g, depending on the specific rheology modifier and the target compound.

This adsorption capability is particularly valuable in environmental applications, where rheological additive can be used to remove organic contaminants from water and soil. The mechanism involves both surface adsorption and partition of organic compounds into the organic phase of the modified clay.Thermal and Environmental Stability

Organic clay exhibits good thermal stability, typically maintaining its structural

integrity and performance characteristics at temperatures up to 200-250°C, depending

on the specific organic modifier used. This thermal stability makes it suitable for

applications involving elevated processing or service temperatures.

In terms of environmental stability, organic bentonite is generally resistant to

degradation under normal environmental conditions. However, the organic components

may be susceptible to oxidation or biodegradation over extended periods, particularly in

harsh environments. The stability can be enhanced through the selection of more

resistant organic modifiers or through additional treatment processes.

Types of Organobentonite Products

versatility of this material and its ability to be tailored for specific applications.

Understanding the different types can help in selecting the most appropriate product for

particular industrial needs.

Classification by Organic Modifier

Quaternary Ammonium-Modified Organobentonites

These represent the most common type of organobentonites, produced by modifying

bentonite with quaternary ammonium compounds such as dimethyl dihydrogenated

tallow ammonium chloride (DMHT) or benzyl dimethyl hydrogenated tallow ammonium

chloride (BDMHT). The length of the alkyl chains in these compounds significantly

influences the properties of the resulting organobentonite, with longer chains typically

providing better compatibility with non-polar systems.

These products excel in organic media such as aliphatic and aromatic solvents, making

them ideal for oil-based drilling fluids, solvent-based coatings, and greases. They

typically require activation with polar additives like acetone, methanol, or propylene

carbonate to achieve optimal dispersion and performance.

Polymer-Modified Organobentonites

These advanced organophilic clays are produced by modifying bentonite with polymeric

compounds such as polyacrylic acid (PAA), polyethylene oxide (PEO), or various

copolymers. The polymer chains can intercalate between the clay layers or adsorb onto

the clay surfaces, creating a hybrid organic-inorganic material with unique properties.Polymer-modified organobentonites often exhibit enhanced thermal stability and

improved compatibility with polymer matrices, making them particularly valuable as

rheological additives in polymer composites and as binders in foundry applications. The

interaction between the polymer and the clay can also result in synergistic effects that

enhance the overall performance of the material.

Classification by Application Medium

Oil-Based Organobentonites

Specifically designed for compatibility with non-polar and moderately polar organic

media, these organobentonites are typically modified with quaternary ammonium

compounds having long alkyl chains. They excel in systems such as mineral oils,

vegetable oils, aromatic solvents, and various petroleum products.

Oil-based organobentonites are widely used as rheological additives in lubricating

greases, oil-based drilling fluids, solvent-based coatings, and printing inks. They provide

excellent thickening, anti-settling, and anti-sagging properties in these applications.

Water-Based Organobentonites

These specialized organobentonites are designed to maintain some degree of

hydrophilicity while incorporating organophilic properties. They are typically produced

using organic modifiers with hydrophilic groups or through partial modification of the

clay.

Water-based organobentonites find applications in water-based coatings, emulsions,

and certain environmental remediation processes. They can provide rheological control

in aqueous systems while also offering some compatibility with organic components in

mixed systems.

Classification by Performance Characteristics

High-Efficiency Organobentonites

These premium products are designed to deliver maximum rheological performance at

lower dosages. They typically undergo additional processing steps to enhance their

dispersion characteristics and rheological efficiency. High-efficiency organobentonites

may require less activation and provide superior performance in demanding

applications.Economy-Grade Organobentonites

These products offer a balance between performance and cost, making them suitable for

applications where extreme rheological control is not required. They typically require

standard activation procedures and may be used at slightly higher dosages to achieve

the desired effects.

Specialty Organobentonites

These include custom-formulated products designed for specific applications or to meet

particular performance requirements. Examples include organobentonites with

enhanced thermal stability for high-temperature applications, those with improved

chemical resistance for aggressive environments, or those with specific surface

treatments for enhanced compatibility with particular systems.

Industrial Applications of Organobentonite

The versatility of organobentonite has led to its adoption across a wide range of

industries, where its unique properties address specific challenges and enhance product

performance. The following sections explore the major application areas and the

specific benefits that organobentonite brings to each.

Coatings and Inks Industry

In the coatings and inks industry, organobentonite serves as a critical rheological

additive that provides multiple benefits to formulations. When properly dispersed in

solvent-based paints, varnishes, and lacquers, organobentonite creates a three

dimensional network structure that imparts thixotropic properties to the system. This

thixotropy prevents settling during storage, reduces sagging during application, and

improves leveling for a smoother finish.

For printing inks, particularly those used in gravure and flexographic printing,

organobentonite controls flow properties to ensure precise transfer of the ink to the

substrate. It prevents bleeding and feathering while maintaining color intensity and

print definition. The anti-settling properties also extend the shelf life of inks by

preventing pigment separation.

Typical dosage levels in coating applications range from 0.5% to 3% by weight,

depending on the specific formulation requirements and the type of organobentonite

used. For optimal performance, the organobentonite is typically pre-dispersed in a

suitable solvent with a polar activator before incorporation into the final formulation.Lubricants and Greases

In lubricating greases, organobentonite functions as a thickening agent that provides

structure and consistency to the formulation. Unlike conventional soap-based

thickeners, organobentonite-based greases offer superior thermal stability, water

resistance, and performance under high shear conditions.

The three-dimensional network formed by organobentonite in mineral or synthetic oils

creates a stable structure that holds the lubricant in place while allowing controlled

release during operation. This structure also provides excellent mechanical stability,

ensuring that the grease maintains its consistency even under severe mechanical

working.

Organobentonite-based greases are particularly valuable in high-temperature

applications, where they can maintain their structure and performance at temperatures

up to 200°C, significantly outperforming many conventional greases. They are widely

used in automotive, industrial, and marine applications where extreme conditions are

encountered.

Environmental Applications

The strong adsorption capabilities of organobentonite make it an effective material for

environmental remediation, particularly for the removal of organic contaminants from

water and soil. When used in wastewater treatment, organobentonite can efficiently

remove oils, greases, phenols, chlorinated compounds, and various other organic

pollutants through a combination of adsorption and partition mechanisms.

In soil remediation, organobentonite can be used as a barrier material to prevent the

migration of organic contaminants or as an amendment to immobilize pollutants in

contaminated soils. The hydrophobic nature of organobentonite allows it to

preferentially bind organic compounds, reducing their bioavailability and potential

environmental impact.

Recent research has also explored the use of organobentonite in the removal of

emerging contaminants such as pharmaceuticals, personal care products, and

endocrine-disrupting compounds from water. The high adsorption capacity and

selectivity for organic compounds make organobentonite a promising material for

addressing these challenging environmental issues.

Foundry Industry

In the foundry industry, organobentonite serves as both a binder and a lustrous carbon

carrier in bentonite-bonded molding sands. The organic modification of bentoniteenhances its binding properties while also providing a source of carbon that improves

the surface quality of castings.

When used in molding sands, organobentonite helps to reduce defects such as veining,

scabbing, and penetration by forming a protective barrier between the molten metal

and the sand mold. The organic components decompose during casting to form lustrous

carbon, which prevents metal penetration and improves the surface finish of the

castings.

The use of organobentonite in foundry applications also offers environmental benefits

by reducing emissions of volatile organic compounds (VOCs) and other harmful

substances during the casting process. This makes it an attractive alternative to

conventional carbon additives such as coal dust or petroleum-based products.

Other Emerging Applications

Beyond the established applications, organo bentonite is finding new uses in various

emerging fields:

• In polymer composites, organophilic clays bentonite serves as a nanofiller that enhances

mechanical properties, thermal stability, and barrier characteristics. The

intercalation or exfoliation of polymer chains between the clay layers creates

nanocomposites with significantly improved performance compared to

conventional filled polymers.

• In pharmaceutical and cosmetic formulations, organobentonite functions as a

rheology modifier, stabilizer, and delivery vehicle for active ingredients. Its ability

to form gels in organic media makes it valuable for controlling the consistency and

release properties of various personal care products.

• In oil and gas drilling, specialized organobentonites are used as rheological

additives in oil-based drilling fluids, providing viscosity control, suspension of drill

cuttings, and stability under high-temperature and high-pressure conditions.

• In adhesives and sealants, organoclays bentonite improves thixotropy, prevents sagging,

and enhances the mechanical properties of the cured products. It is particularly

valuable in formulations that must maintain their position after application but

before curing.

Advantages of Organobentonite in Industrial Processes

The incorporation of organobentonite into industrial formulations and processes offers

numerous advantages that contribute to improved product performance, enhancedprocess efficiency, and reduced environmental impact. Understanding these advantages

helps to appreciate the value proposition of clay in various applications.

Enhanced Product Performance

One of the primary advantages of rheological bentonite is its ability to significantly enhance

the performance characteristics of the products in which it is incorporated. In coatings

and inks,rheological additive improves application properties, prevents settling and

sagging, and enhances the overall appearance of the finished product. The thixotropic

properties it imparts allow for easier application while ensuring that the coating remains

in place on vertical surfaces.

In lubricating greases, organobentonite provides exceptional mechanical stability, high

temperature performance, and water resistance. Greases formulated with

organobentonite maintain their consistency under severe operating conditions,

extending the service life of lubricated components and reducing maintenance

requirements.

For environmental applications, the high adsorption capacity and selectivity of

organobentonite for organic compounds result in more efficient removal of

contaminants from water and soil. This leads to improved remediation outcomes and

better protection of environmental resources.

Process Efficiency and Simplification

The use of organobentonite can streamline manufacturing processes and improve

operational efficiency in several ways. Its effectiveness at low dosages means that less

material is required to achieve the desired rheological properties, reducing raw material

costs and simplifying inventory management.

The thixotropic behavior provided by organobentonite allows for easier processing

during manufacturing. For example, in coating production, the reduced viscosity under

shear makes mixing, pumping, and filling operations more efficient, while the increased

viscosity at rest prevents settling during storage.

In foundry applications, organobentonite can serve dual functions as both a binder and

a lustrous carbon carrier, eliminating the need for separate additives and simplifying the

molding sand formulation process. This multifunctionality reduces the number of

ingredients that need to be handled, stored, and controlled.Cost-Benefit Analysis

While organobentonite may have a higher unit cost compared to some conventional

additives, a comprehensive cost-benefit analysis often reveals significant economic

advantages. The higher efficiency of organobentonite means that lower dosages are

required to achieve the desired effects, potentially resulting in overall cost savings.

The improved performance and extended service life of products formulated with

organobentonite can also translate into economic benefits for end-users. For example,

lubricating greases with better high-temperature stability require less frequent

replacement, reducing maintenance costs and equipment downtime.

In environmental applications, the high adsorption capacity of organobentonite can

make remediation processes more cost-effective by reducing treatment time and

resource requirements. The ability to regenerate and reuse organobentonite in some

applications further enhances its economic value proposition.

Environmental Benefits

The environmental advantages of organobentonite extend beyond its direct applications

in environmental remediation. The efficiency of organobentonite at low dosages means

that less material is required, reducing resource consumption and waste generation.

In foundry applications, organobentonite-based binders can reduce emissions of volatile

organic compounds (VOCs) and other harmful substances during the casting process.

This contributes to improved air quality in the workplace and reduced environmental

impact of foundry operations.

The natural origin of the base bentonite clay, combined with the potential for using bio

based organic modifiers, positions organobentonite as a more sustainable alternative to

some synthetic rheological additives. Ongoing research into environmentally friendly

organic modifiers continues to enhance the sustainability profile of organobentonite

products.

Comparison with Alternative Products

When compared to alternative rheological additives and performance enhancers,

organobentonite often offers a superior balance of properties and benefits. Unlike many

synthetic thickeners, organobentonite provides true thixotropic behavior, with rapid

recovery after shearing and excellent long-term stability.

In comparison to fumed silica, another common rheological additive, organobentonite

typically requires lower dosages to achieve similar thickening effects and offers bettercontrol of sag and settling. It also generates less dust during handling, improving

workplace safety and reducing product losses.

For environmental applications, organobentonite offers advantages over activated

carbon in terms of cost and selectivity for organic contaminants. While activated carbon

has a higher surface area and broader adsorption spectrum, organobentonite’s affinity

for organic compounds makes it more efficient for targeted removal of specific

contaminants.

How to Select the Right Organobentonite for Your

Application

Choosing the most appropriate organobentonite product for a specific application

requires careful consideration of various factors, including the nature of the application

medium, the desired performance characteristics, and the processing conditions. The

following guidelines can help in making an informed selection.

Application Requirement Analysis

The first step in selecting an organobentonite product is to clearly define the

requirements of the application. This includes identifying:

• Any regulatory or environmental constraints

A comprehensive understanding of these requirements provides the foundation for

selecting an organobentonite product that will deliver the desired performance.

Key Performance Parameters

Several key parameters should be considered when evaluating organobentonite

products:

• Compatibility with the application medium: Different organobentonites are

designed for specific types of media. For non-polar systems like mineral oils or

aliphatic solvents, highly organophilic grades are typically required. For more polar

systems, moderately modified grades may be more suitable.• Activation requirements: Some organobentonites require activation with polar

additives to achieve optimal dispersion and performance. The availability and

compatibility of these activators with the overall formulation should be

considered.

• Efficiency: The dosage required to achieve the desired rheological properties

varies among different organobentonite products. Higher-efficiency grades may

have a higher unit cost but require lower dosages, potentially resulting in overall

cost savings.

better dispersion and higher efficiency but may be more difficult to incorporate.

The ease of dispersion is particularly important in production environments with

limited high-shear mixing capabilities.

• Thermal and chemical stability: For applications involving high temperatures or

aggressive chemicals, the stability of the organobentonite under these conditions

is a critical consideration.

Compatibility Considerations

The compatibility of organobentonite with other components in the formulation is

essential for achieving optimal performance. Key compatibility considerations include:

• Interactions with surfactants and dispersants: Some surfactants and dispersants

can interfere with the network structure formed by organobentonite, reducing its

effectiveness. Compatibility testing is recommended when these components are

present.

• pH sensitivity: While organobentonites are generally less sensitive to pH than

unmodified bentonites, extreme pH conditions can still affect their performance.

The pH range of the application should be considered in the selection process.

• Solvent polarity: The effectiveness of organobentonite is influenced by the

polarity of the solvent system. Matching the organobentonite type to the solvent

polarity is crucial for optimal performance.

• Presence of competing adsorbates: In applications involving multiple organic

compounds, competitive adsorption can affect the performance of

organobentonite. Understanding these interactions is important, particularly in

environmental applications.Testing and Validation Methods

Before finalizing the selection of an organobentonite product, laboratory testing and

validation are essential to confirm its suitability for the specific application. Common

testing methods include:

• Rheological measurements: Viscosity profiles at different shear rates, yield value

determination, and thixotropy assessment provide insights into the rheological

behavior of the organobentonite in the application medium.

• Dispersion quality assessment: Microscopic examination or filtration tests can

evaluate the degree of dispersion achieved, which directly affects performance.

• Stability testing: Accelerated aging tests under relevant conditions (temperature,

light, humidity) help predict the long-term stability of formulations containing

organobentonite.

• Application-specific performance tests: These may include sag resistance for

coatings, water resistance for greases, or adsorption efficiency for environmental

applications.

• Pilot-scale trials: Before full-scale implementation, pilot trials under actual

production conditions are recommended to validate laboratory findings and

identify any scale-up issues.

Optimization Recommendations

To maximize the performance of organobentonite in your application, consider the

following optimization strategies:

• Pre-dispersion: Preparing a pre-gel of organobentonite in a portion of the solvent

with appropriate activators before incorporation into the final formulation often

improves dispersion and performance.

• Activation optimization: The type and amount of polar activator can significantly

influence the efficiency of organobentonite. Optimization of the activator system

can enhance performance while minimizing costs.

• Processing conditions: The temperature, mixing speed, and duration of the

dispersion process all affect the final performance. Optimization of these

parameters can improve efficiency and consistency.• Synergistic combinations: In some applications, combining organobentonite with

complementary rheological additives can provide enhanced performance and cost

effectiveness.

Best Practices for Organobentonite Handling and

Application

Proper handling and application of organobentonite are essential for achieving optimal

performance and maximizing the value of this versatile material. The following best

practices provide guidance for storage, dispersion, and application of organobentonite

products.

Storage and Handling Recommendations

To maintain the quality and performance of organobentonite products, proper storage

conditions are essential:

• Store in a cool, dry place away from direct sunlight and moisture. Exposure to

moisture can affect the organobentonite’s performance, particularly in solvent

based applications.

• Keep containers tightly sealed when not in use to prevent contamination and

moisture absorption. For bulk storage, ensure that silos or bins are properly sealed

and protected from the elements.

• Implement appropriate inventory management practices, using older stock first

(first-in, first-out) to minimize storage time. While organobentonite products are

generally stable, prolonged storage may affect their performance in some

applications.

• When handling organobentonite powder, use appropriate dust control measures

and personal protective equipment. Although organobentonite is not classified as

hazardous, dust inhalation should be avoided as a general precaution.

• Allow cold material to warm to room temperature before opening containers to

prevent condensation, which can affect the powder’s flowability and dispersion

characteristics.Dispersion and Activation Techniques

Achieving proper dispersion of organobentonite is crucial for its performance as a

rheological additive. The following techniques can help ensure optimal dispersion:

• For solvent-based systems, pre-wet the organobentonite with a polar activator

(such as propylene carbonate, methanol, or a mixture of water and low-molecular

weight alcohols) before adding it to the main solvent. The typical ratio is 30-60%

activator based on the weight of organobentonite.

• Allow sufficient time (typically 5-15 minutes) for the activator to interact with the

organobentonite before adding the mixture to the main solvent. This pre-activation

step significantly improves dispersion efficiency.

• Use high-shear mixing equipment such as high-speed dispersers, rotor-stator

mixers, or ball mills to achieve complete dispersion. The high shear forces help to

separate the clay platelets and develop the three-dimensional network structure.

• For maximum efficiency, add the pre-activated organobentonite to the solvent

before incorporating other components such as pigments, fillers, or resins. This

allows the organobentonite to fully develop its structure without interference.

• Monitor the dispersion process using visual inspection, fineness of grind

measurements, or rheological tests to ensure that complete dispersion has been

achieved. Incomplete dispersion can result in reduced efficiency and performance

issues.

Addition Methods and Proportioning

The method of adding organobentonite to formulations and the proportioning of

components can significantly impact performance:

• The pre-gel method, where organobentonite is first dispersed in a portion of the

solvent to form a concentrated gel before being incorporated into the final

formulation, often provides the best results. Typical pre-gel concentrations range

from 5% to 10% organobentonite by weight.

• For direct addition methods, introduce the organobentonite slowly into the vortex

created by a high-speed mixer to prevent clumping and ensure even distribution.

Avoid dumping large amounts at once, as this can lead to agglomeration and poor

dispersion.• The dosage of organobentonite should be carefully controlled based on the

specific application requirements. Starting with the manufacturer’s recommended

dosage and adjusting based on performance testing is a good approach.

• In formulations containing multiple additives, the order of addition can be critical.

Generally, organobentonite should be added and fully dispersed before

introducing components that might interfere with its dispersion, such as

surfactants or wetting agents.

• For applications requiring precise control of rheological properties, consider

implementing automated dosing systems to ensure consistency in the amount of

organobentonite added to each batch.

Common Issues and Solutions

Even with proper handling and application procedures, certain issues may arise when

working with organobentonite. Here are some common problems and their solutions:

• Poor dispersion: Manifested as visible particles, grittiness, or reduced efficiency.

Solutions include increasing shear during mixing, optimizing the activator system,

or switching to a more easily dispersible grade of organobentonite.

• Compatibility issues: Indicated by flocculation, separation, or loss of rheological

properties when combined with other formulation components. Solutions include

adjusting the order of addition, modifying the activator system, or selecting an

alternative organobentonite grade more compatible with the specific formulation.

• Insufficient thickening: When the organobentonite does not provide the desired

viscosity or thixotropy. Solutions include increasing the dosage, ensuring complete

dispersion, optimizing the activator system, or selecting a higher-efficiency grade.

• Excessive thickening: When the formulation becomes too viscous for processing

or application. Solutions include reducing the dosage, adjusting the activator level,

or selecting a lower-efficiency grade.

• Syneresis or bleeding: The separation of liquid from gels or greases containing

organobentonite. Solutions include adjusting the organobentonite-to-liquid ratio,

modifying the activator system, or incorporating complementary thickeners.Safety Handling Guidelines

While organobentonite products are generally considered safe for industrial use,

appropriate safety measures should be implemented:

• Review the Safety Data Sheet (SDS) for specific handling precautions and

emergency procedures related to the particular organobentonite product being

used.
