High-Performance 2K Epoxy Primer System | Blister-Free Coating for Multi-Substrates

The two-component system combining WL-AD203 water-based epoxy resin with WL-AC049 curing agent delivers coatings with broad substrate compatibility, 1000+ hour salt spray resistance, and long-term blister-free performance.

WL-AD203 waterborne epoxy resin

‌WL-AD203 Waterborne Epoxy Dispersion‌ delivers high-performance coatings when crosslinked with compatible epoxy curing agents. Designed for corrosion-resistant primers and metal floor coatings, its key features include rapid surface drying, wet-on-wet process compatibility, accelerated hardness development, and extended pot life.

WL-AC049 Epoxy curing agent

‌ WL-AC049 Water-Dispersible Polyamine Adduct‌ is engineered for formulating high-performance water-based epoxy coatings when crosslinked with epoxy emulsions. Designed for corrosion-resistant primers and metal floor coatings, it delivers exceptional salt spray/water resistance, superior wet adhesion, and extended pot life.
