Waterborne Epoxy Intermediate Coating Curing Agent DCA-8186

Introduction

DCA-8186 is a modified polyamide curing agent designed for ambient temperature curing in waterborne epoxy systems. It possesses exceptional hydrophilicity and emulsion stability, making it suitable for epoxy emulsions and standard liquid epoxy resins, showing excellent compatibility. DCA-8186 is particularly recommended for cementitious mortars and waterborne epoxy intermediate coatings. It offers excellent workability during application, a longer working time, minimal adhesion to trowels, reduced tendency for mortar drags, fewer entrapped air voids in the mortar, high strength, and strong substrate adhesion.
