Organoclay based adhesives

Organic bentonite, as a purified and modified organic clay rheology additive, derives its core advantages from its unique molecular structure design.

It is based on natural montmorillonite clay, which is modified through organic cation exchange reactions, transforming the originally hydrophilic clay surface into a hydrophobic one.

This structural modification enables it to perfectly compatible with synthetic oil-based systems, particularly excelling in highly polar base oils such as vegetable oils and polyester oils. Compared to unmodified bentonite, its interlayer distance expands from approximately 1 nm to 2–3 nm, providing more adsorption sites for base oil molecules and forming a stable colloidal structure.

In grease production, this structure effectively resists mechanical shear forces, ensuring the product maintains stable viscosity during long-term use and providing continuous, reliable lubrication protection for mechanical components such as gears and bearings.

Organoclay-based adhesives deliver non-sag application, excellent substrate wetting, and high-temperature bond retention; the Pillar context is organoclay rheology modifier for adhesive systems.
