  • Using

Organic Bentonite can be added directly in powder under high shear condition. Addition level is commonly 0.1%~1.0% of total formulation by weight. Polar activator need to achieve better performance.

  • The addition procedure as below.
  1. Add resin in solvent.
  2. Add CP-138Y under slow agitation.
  3. Disperse under high speed for 10-15 minutes.
  4. Add polar activator.
  5. Disperse under high speed for 10-15 minutes.
  6. Add wetting agent and other additive.
  7. Grinding and next procedure.

 If to make pre-gel, better efficiency can be achieved. Addition level in pre-gel is 5%-8% of total pre-gel in weight.

  • Pre-gel procedure as below.
  1. Add solvent or solvent mixture.
  2. Add CP-138Y under slow agitation.
  3. Disperse under high speed for 5-10 minutes.
  4. Add polar activator.
  5.  Disperse under high speed for 5-10 minutes.

Polar activator is suggested to be ethanol and water (95 and 5), methanol and water (95 and 5) or acetone.  

  • Package

Kraft bag or kraft complex interior with PE or customized.


Organic Bentonite should be stored in dry place.
