K-PURE CXC-1821

K-PURE CXC-1821 is a quaternary ammonium blocked super acid catalyst, designed to provide similar performance to SbF6 type catalysts, but without the antimony. CXC-1821 can catalyze the reaction of epoxy resins, ring opening of cyclic ether groups, and polymerization of monomers sensitive to cationic polymerization. CXC-1821 can also be used as a thermal acid generator in systems that require pH control at elevated temperatures.

ADVANTAGES:
Fast cure response with no out-gassing
