CP-180 is an organo clay (modified montmorillonite), designed especially for use in solvent based system including intermediate and low polarity range organic liquid..
Composition Organic derivative of a montmorillonite clay
Appearance Fine powder, white
Moisture content (105℃,2hr) ≤3.5%
Loss on ignition (1000℃) 29%-32%
Bulk density 0.53g/cm3
Fineness (<74μm, %) ≥98%
CP-180 is used in the following applications:
Paints & coatings with solvent of low to medium polarity
Lubricant Grease, ink, sealant
Oil drilling mud
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.
