Organoclay CP-180 for Paints

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:

Ÿ   Paints & coatings with solvent of low to medium polarity

Ÿ   Powder Coating

Ÿ   Lubricant Grease, ink, sealant

Ÿ   Cosmetic

Ÿ   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.
