Properties
Composition Organic derivative of a montmorillonite clay
Appearance Fine powder, light yellow
Moisture content (105℃,2hr) ≤3.5%

Bulk density 0.53g/cm3
Fineness (<74μm, %) ≥98%
Advantages
High gelling efficiency
Light color gel
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
CP-34 is used in the following applications:
Marine paint, Industrial paint, heavy-duty, anticorrosion paint such as bituminous coatings, polyester paints, Alkyd paints.
Sealant
Inks
Grease
Unsaturated polyester putty
Using
CP-34 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 40%~50% of CP-34 in weight. If in xylene system, addition level of polar activator is about 30%-40% of CP-34 in weight.
Pre-gel is made as below procedure.
Charge solvent to mill
Slowly add CP-34(6-10% by weight of total pregel) to mill under agitation.
Mix at high speed for 5 minutes.
Add polar activator.
Mix at high speed for 5 minutes.
