Our high-purity Organoclay Rheological Additive, derived from calcium-modified bentonite clay powder, is designed to enhance the performance of lubricating greases. When incorporated into grease formulations, this organophilic clay provides excellent high-temperature resistance, working stability, and water resistance, ensuring reliable performance under demanding conditions.
CP-40 Organoclay for Grease Lubricating
CP-40 is a modified bentonite organoclay specifically developed for use in solvent-based systems. It is effective across a wide range of solvents, from low polarity to medium-high polarity, offering superior thickening and rheological control. CP-40 delivers enhanced stability and improved suspension properties, making it an ideal choice for a variety of industrial and commercial applications.

Our Organic bentonite is used in：
- Marine paint, Industrial paint, heavy-duty, anticorrosion paint such as bituminous coatings, epoxy paints, chlorinated rubber paints
- Grease
- Inks
- Sealant
Storage of CP-40 Organoclay for Grease Lubricating
Modified Bentone CP-40 Store in a dry, well-ventilated area with temperature of 0℃-30℃. Keep container closed. The quality guarantee period is 24 months.
Organic Bentonite Powder Using
CP-40 disperses under high shear and requires a polar activator for best efficiency. Heat is not required to obtain good dispersion. Addition levels are typically in 0.2%~2.0%. Polar activator (95% Ethanol or 95% Methanol) is needed. Normally addition level of polar activator is recommended to be 45%~60% of CP-40 in weight. If in xylene system, addition level of polar activator is about 30%-40% of CP-40 in weight.
Pre-gel is made as below procedure.
- Charge solvent to mill
- Slowly add CP-40 (6-10% by weight of total pre-gel) to mill under agitation.
- Mix at high speed for 5 minutes.
- Add polar activator.
- Mix at high speed for 5 minutes.
