Abstract

Claims (30)

1 . 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.

2 . The method of claim 1 , wherein curing the dried system is accomplished using ultraviolet (UV) energy, Light Emitting Diode (LED) energy, electron beam (EB) energy, a thermal crosslinking mechanism, and/or an oxidative crosslinking mechanism.

3 . The method of claim 1 , wherein the pH of the two-phase system changes less than 0.6 over 60 days.

4 . The method of claim 1 , wherein the crosslinkers are monomers and/or oligomers.

5 . The method of claim 1 , wherein the acrylic emulsion is anionic or cationic.

6 . The method of claim 1 , further comprising applying the two-phase system to a surface before removing the liquid from the two-phase system to create the dried system including uncrosslinked crosslinkers.

7 . The method of claim 1 , wherein the film including crosslinked crosslinkers is a continuous film.

8 . The method of claim 6 , wherein the dried system including uncrosslinked crosslinkers is a film.

9 . The method of claim 6 , wherein the dried system including uncrosslinked crosslinkers is a continuous film.

10 . The method of claim 1 , further comprising incorporating at least one photoinitiator before curing the dried system to create the final system including the film including the crosslinked crosslinkers.

11 . The method of claim 1 , further comprising incorporating at least one additive, wherein the at least one additive is at least one defoamer, at least one surface wetting aid, at least one matting agent, at least one organic filler, at least one inorganic filler, at least one pigment, at least one rheology modifier, at least one pH buffer, at least one algaecide, at least one biocide, at least one coalescing solvent, at least one co-solvent, at least one dispersing aid, at least one wax, at least one adhesion promoter, at least one anti-static agent, and/or at least one anti-corrosion agent.

12 . The method of claim 1 , wherein the (meth)acrylate crosslinker is incorporated up to a weight ratio of 1:1 acrylic emulsion solids to the (meth)acrylate crosslinker.

13 . 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.

14 . The method of claim 13 , wherein the emulsion is an acrylic emulsion and wherein the crosslinker is an acrylate crosslinker.

15 . The method of claim 13 , wherein the emulsion includes at least one permanent counterion.

16 . The method of claim 13 , further comprising incorporating at least one photoinitiator prior to applying the two-phase system to the surface.

17 . The method of claim 13 , wherein the viscosity of the two-phase system is lower than the viscosity of the emulsion.
