The present system is a waterborne coating composition comprising a low
VOC (<50 g/l) acrylic epoxy coating which is capable of high build
coating formation (>12 mils) without foaming. The coating composition
may be made, stored and transported as a two-part composition, where each
part is a pourable liquid. The waterborne acrylic epoxy composition cures
under ambient condition to give tenacious adhesion to a variety
substrates. The coating system, described herein, is designed as an
ambient cure system, but may also be cured at elevated temperatures. The
two component emulsion composition is useful for coating applications.
One component is an emulsion comprised of a blend of a hydroxy functional
acrylic polymer co-reactant, suitable additives, pigments and epoxy resin
The second component is a waterborne amine hardener for curing or
crosslinking the first component.
