| Message: | GENERAL INFORMATION
BK-1C is an organically modified bentonite designed for use in low to medium polarity solvent system.
ADVANTAGES
☆Increases viscosity and imparts thixotropic properties.
☆Prevents hard settling during storage.
☆ Exerts strong film reinforce action in organic systems.
INCORPORATIONS
BK-1C requires high shear dispersion in the solvent or resin/solvent blend as well as a chemical activator. It is added to the solvent or resin/solvent and dispersed under shear for 10 minutes. Following that a polar activator is added and mixed an additional 10 minutes to ensure complete activation.Cowles-type dissolvers, sand, ball or three roll mills are all suitable.
RECOMMENDED LEVELS
BK-1C use level depends on organic system but typically between 0.5%-3.0% by weight of the total system, depending upon the degree of thickening or other properties desired. Laboratory testing is recommended to determine optimal level.
