K-CURE 129B
K-CURE 129B is a strong acid catalyst supplied at 50% in a mixture of alcohols. It is a very strong acid catalyst designed to produce fast cures with adequate pot life in two component acid curing lacquers. Because of its corrosive nature, however, K-CURE 129B is not recommended for use on metal substrates.
