Organoclay It Is Solvent Based Used in Grease

Product Description



CP-40 is an organo clay (modified bentonite), designed especially for use in solvent based system. It can be used widely in solvents from low polarity to medium-high polarity.



Composition                                  Organic derivative of a montmorillonite clay

Appearance                                   Fine powder, light yellow

Moisture content (105℃,2hr)         ≤3.5%

Loss on ignition (1000℃)               28%-31%

Bulk density                                   0.53g/cm3

Fineness (<74μm, %)                    ≥98%


 CP-40 is used in the following applications:

Ÿ   Marine paint, Industrial paint, heavy-duty, anticorrosion paint such as bituminous coatings, epoxy paints, chlorinated rubber paints

Ÿ   Grease

Ÿ   Inks

Ÿ   Sealant


CP-40 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 45%~60% of CP-40 in weight. If in xylene system, addition level of polar activator is about 30%-40% of CP-40 in weight.

Pre-gel is made as below procedure.

1. Charge solvent to mill

2. Slowly add CP-40 (6-10% by weight of total pre-gel) to mill under agitation.

3. Mix at high speed for 5 minutes.

4. Add polar activator.

5. Mix at high speed for 5 minutes.
