Organoclay for sealant formulations

The fineness index directly determines the dispersion efficiency and final product quality of organic bentonite. A standard where over 98% of particles are smaller than 74μm ensures excellent dispersion performance.

Laser particle size analysis shows that the product has a concentrated particle size distribution with no large particle impurities, with 70% of particles smaller than 30μm. This fine particle size allows it to quickly wet in the base oil, achieving a wetting rate of 95% within 5 minutes.

Comparative experiments show that products with insufficient fineness (only 90% passing 74μm) have extended dispersion times up to 30 minutes and tend to form hard agglomerates, resulting in a gritty texture in the grease.

In precision bearing lubrication, coarse particles can cause abrasive wear, reducing bearing lifespan by 30%. During production, particle size is precisely controlled through an air-jet milling process, and each batch undergoes sieve testing to ensure compliance with particle size specifications.

Clay-based organoclay thickeners in grease formulations provide stable gel structure, high dropping point, and oxidation resistance across a wide temperature range; full product specifications and grease application data are at organoclay for greases — clay-based thickener performance data. Grease formulation guidelines, including dosage, shear stability, and mixing procedures, are covered in organoclay-based greases — formulation and application guide.
