Detailed Description

organo clay (modified bentonite) CP-40 counter to Bentone 34, designed especially for use in solvent based system. It can be used widely in solvents from low polarity to medium-high polarity.

Organic Modified Bentonite Clay Cp-40

Advantages

High gelling efficiency.
Wide application range, it can be applied in all low, middle and high polarity range.
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.

Application

Marine paint, Industrial paint, heavy-duty, anticorrosion paint such as bituminous coatings, epoxy paints, chlorinated rubber paints.
Inks. Grease.
Sealant. Unsaturated polyester putty.

Using
organo clay  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 organo clay  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.
