Organic Bentonite with good self-activated property | Organoclay
CP-27 is an organo clay (modified montmorillonite), designed especially for use in solvent based system. It is used especially in solvents of high polarity.
It is suggested to be used to replace Bentone27 and Bentone57.
Application
Marine paint, Industrial paint, heavy-duty, anticorrosion paint (especially for epoxy paint).
Grease.
Ink.
Sealant.
Unsaturated polyester putty.
Advantages
High gelling efficiency
Produce reproducible thixotropic consistency over a wide temperature range
Imparts particle suspension, preventing hard settling of pigment and fillers.
Exerts strong film reinforcing action in organic binder systems.

Using
CP-27 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%. Normally addition level of polar activator (95% Ethanol or 95% Methanol) is recommended to be 45%~60% of CP-27 in weight.
