Краткое введение:
HENSAMINE 7002S is a water-soluble modified amine curing agent designed to be used with epoxy emulsions and liquid epoxy resins. Suitable for primers, intermediate coats, and topcoats under ambient curing, it offers low viscosity, long pot life, excellent surface coating performance, scratch resistance, and good polishability.
