Water-dispersed epoxy/acrylic coatings for plastic substrates

A water-dispersed paint coating composition particularly useful for plastic substrates such as polystyrene foam comprises a polymeric binder of a functional acrylic copolymer and epoxy resin. Preferably, the epoxy resin is a coreaction product containing sorbitol. The polymers are water-dispersed an...

Beschreibung
Zusammenfassung:	A water-dispersed paint coating composition particularly useful for plastic substrates such as polystyrene foam comprises a polymeric binder of a functional acrylic copolymer and epoxy resin. Preferably, the epoxy resin is a coreaction product containing sorbitol. The polymers are water-dispersed and are adapted to cure and crosslink at ambient temperatures.
