Waterborne Epoxy Topcoat Curing Agent DCA-8187
Introduction
DCA-8187 is a special modified curing agent designed for ambient temperature curing in waterborne epoxy systems. It possesses good hydrophilicity and emulsification properties, making it suitable for epoxy emulsions and standard liquid epoxy resins, demonstrating excellent compatibility. DCA-8187 is particularly recommended for waterborne epoxy topcoats, containing no organic solvents, releasing no formaldehyde, and being environmentally safe. When combined with liquid epoxy resins, it yields a glossy anti-slip surface; when combined with epoxy emulsions, it produces a softly gleaming matte finish.
