WX-K2100-40 Modified epoxy resin dispersion
Part I: Introduction
★Water-dispersed epoxy ester resin designed for water-borne self-drying paint and water-borne low-temperature baking paint
★It is necessary to add water-based drier to assist cross-linking when It is airdrying。
★Adding water-based polyurethane can made 2k finish Or Adding different amino resin to make baking finish。
★Excellent performance in salt spray resistance, water resistance, weather resistance , high gloss and fullness。
★Excellent adhesion on all kinds of metal substrate
★Good hydrolysis resistance,good stability for water based paint.
