Abstract
The present invention provides a method of making an aqueous coating composition comprising an aqueous dispersion of an epoxy acrylate resin and a polymerized reactive diluent. The aqueous coating composition preferably has a volatile organic compound content of no greater than 0.4 kilogram per liter of solids.
Claims20
A coating composition comprising an interpenetrating polymer network, of a polymerized reactive diluent and an epoxy acrylate resin, dispersed in water;
- the coating composition prepared by the steps comprising:
- dispersing a reactive diluent and said epoxy acrylate resin in water;
- and subsequently polymerizing the reactive diluent in the presence of the epoxy acrylate resin, yielding said interpenetrating polymer network dispersed in water;
- wherein the epoxy acrylate resin is the reaction product of an epoxy material and an acrylic resin;
- wherein the reactive diluent is essentially non-reactive with the epoxy material used to form the epoxy acrylate resin;
- and
- wherein the coating composition has a volatile organic compound content of no greater than 0.4 kilogram per liter of solids.
