Organoclay CP-180B It Is Used in Solvent Based System with Polarity Range Organic Liquid

CP-180B

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%

Ÿ   Exerts gelling efficiency over a wide range of intermediate and low polarity

Ÿ   Easy dispersing

Ÿ   The gel is colourless and of high clarity

Ÿ   Produce reproducible thixotropic consistency over a wide temperature range

Ÿ   Imparts particle suspension, sag resistance without impairing flow and leveling, preventing hard settling of pigment and filler

Ÿ   Exerts strong film reinforcing action in organic binder systems

  CP-180B is used in the following applications:

Ÿ   Transparent coatings

Ÿ   Lubricant Grease, ink, sealant

Ÿ   Cosmetic

Ÿ   Nano-composite

Ÿ    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.
