Abstract
The present invention provides a method for crosslinking an acrylic emulsion with a (meth)acrylate monomer or a (meth)acrylate oligomer including adding a base acrylic emulsion to a vessel, adding at least one (meth)acrylate crosslinker to the vessel, incorporating the at least one (meth)acrylate crosslinker into the base acrylic emulsion to create a two-phase system including water and a phase including crosslinkers of the at least one (meth)acrylate crosslinker inside acrylic emulsion particles of the base acrylic emulsion, applying the two-phase system to a surface, and curing the two-phase system to create a final system including a continuous film and crosslinked crosslinkers.
