Organoclay Application
CP-40 is used in the following applications:
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.
Package

Storage
CP-40 has a shelf life of 2 years, and should be stored in ventilated cool and dry place.
