CP-27A is organic modified bentonite clay. It is used especially in high polarity resins such as epoxy and high alcohol percentage solvent systems.

Using

It disperses under high shear and requires a polar activator and gel for best efficiency.

Heat is not required to obtain good dispersion.

The addition level of CP-27A is 0.2%~2.0%.
