CP-27 Organic Bentonite Rheological Additive

CP-27 is an organoclay (tetraallkyl ammonium bentonite) for solvent-based systems of high polarity. It is with high gelling efficiency over high polarity organic liquids, especially in aromatic, alcohol, ketone, and the compounds of above. It produces reproducible thixotropic consistency over a wide temperature range, and imparts particle suspension, preventing hard settling of pigment and fillers. It could exerts strong film reinforce action in organic binder systems. Is an equivalent to Bentone 27, Tixogel® VZ.

CP-27 organic bentonite requires the high shear condition and the polarity activator to enhance its dispersion and viscosity reinforcement according to the following steps:

1. Vehicle/solvent (mix)

2. CP-27 (mix 10 minutes)

3. Chemical (polar) activator (mix 5 to 10 minutes) ( Methanol/water(95/5): 33% of CP-27 / Ethanol/water(95/5): 33% of CP-27/ Acetone: 50% of CP-27)

4. Surfactant (if any)

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

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