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 film and crosslinked crosslinkers.
Claims17
A method for crosslinking an emulsion comprising:
- adding an acrylic emulsion to a vessel;
- adding a (meth)acrylate crosslinker to the vessel;
- incorporating the (meth)acrylate crosslinker into the acrylic emulsion to create a two-phase system;
- removing a liquid from the two-phase system to create a dried system;
- and
- curing the dried system to create a final system including a film including crosslinked crosslinkers;
- and
- wherein the viscosity of the two-phase system is lower than the viscosity of the acrylic emulsion.
A method for crosslinking an emulsion comprising:
- adding an emulsion to a vessel;
- adding a crosslinker to the vessel;
- incorporating the crosslinker into the emulsion to create a two-phase system;
- applying the two-phase system to a surface;
- removing water from the two-phase system to create a dried system and
- curing the dried system to create a final system including a film including crosslinked crosslinkers;
- and
- wherein the pH of the two-phase system changes less than 0.6 over 60 days.
