CP-180B is an organo clay (modified montmorillonite), designed especially for use in solvent based system including intermediate and low polarity polarity range organic liquid. It is an improved grade of CP-180. It is more fine, and easier to be dispersed compared with CP-180.
Composition Organic derivative of a montmorillonite clay
Appearance Fine powder, light yellow
Moisture content (105℃,2hr) ≤3.5%
Loss on ignition (1000℃) 29%-32%
Bulk density 0.53g/cm3
Fineness (<74μm, %) ≥98%
CP-180B is used in the following applications:
Lubricant Grease, ink, sealant
Replacement of fumed silica
CP-180B 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-180B in weight.
