Organoclay (modified Bentonite) CP-34 It Can Be Used Widely in Solvents From Low Polarity To Medium-high Polarity.

CP-34

CP-34 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%-30%

Bulk density                                    0.53g/cm3

Fineness (<74μm, %)                     ≥98%

     CP-34 is used in the following applications:

Ÿ   Marine paint, Industrial paint, heavy-duty, anticorrosion paint such as bituminous coatings, polyester paints, Alkyd paints.

Ÿ   Sealant

Ÿ   Inks

Ÿ   Grease

Ÿ   Unsaturated polyester putty

CP-34 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 40%~50% of CP-34 in weight. If in xylene system, addition level of polar activator is about 30%-40% of CP-34 in weight.

Pre-gel is made as below procedure.

1.    Charge solvent to mill

2.    Slowly add CP-34(6-10% by weight of total pregel) to mill under agitation.

3.    Mix at high speed for 5 minutes.

4.    Add polar activator.

5.    Mix at high speed for 5 minutes.
