CP-27 organic bentonite rheological additive

Product Description:

The CP-27 can be easily dispersed into powder with favorable fineness even in very short time. It is a kind of white powder with high gel transparency and good performance in constancy reinforcement, thixotropic and anti-depositing. It has the gelatin capability to medium to high polarity systems as well as various hydrogenated oil and the composite linking substance. This model of product is equivalent to Bentone27.

Usage:

The CP-27 product requires the high shear condition and the polarity activator to enhance its dispersion and viscosity reinforcement according to the following dispensation:

1. Methanol/water(95/5): 33% of CP-27

2. Ethanol/water(95/5): 33% of CP-27

3. Acetone: 50% of CP-27

CP-27 organic bentonite is typically added as follows:

1. Vehicle/solvent (mix)

2. CP-27 (mix 10 minutes)

3. Chemical (polar) activator (mix 5 to 10 minutes)

4. Surfactant (if any)

5. Pigment(s) (disperse to desired N.S.)

6. Let down
The amount of CP-27 should account 0.3-2% of the total amount of the system, which is determined according to the test.
