China Modified Bentonite Counter to Bentone 38

Solvent based Organoclay Rheological Additive CP-180
CP-180 is an organo clay (modified montmorillonite) counter to Bentone 38, designed especially for use in solvent based system including intermediate and low polarity range organic liquid.
Advantages
Exerts gelling efficiency over a wide range of intermediate and low polarity.
Easy dispersing.
The gel is colourless and of high clarity.
Produce reproducible thixotropic consistency over a wide temperature range
Imparts particle suspension, sag resistance without impairing flow and leveling, preventing hard settling of pigment and fillers.
Exerts strong film reinforcing action in organic binder systems.

Using
CP-180 disperses under high shear and requires a polar activator (30%~40%) 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 30%~40% of CP-180 in weight.
