SURFACE COATING COMPOSITIONS
Described herein are surface coating composition comprising: a UV curable urethane or acrylate having one or more phosphate ester moieties; and a silicone acrylate; along with methods of making and using same.
1 . A surface coating composition comprising:
a UV curable urethane or acrylate having one or more phosphate ester moieties; and
a silicone acrylate.
2 . The composition of claim 1 , comprising from about 1 wt. % to about 40 wt. % of the UV curable urethane or acrylate.
3 . The composition of claim 1 , further comprising a fluoropolymer.
4 . The composition of claim 3 , comprising from about 0.1 wt. % to about 40 wt. % of the flouropolymer.
5 . The composition of claim 2 , wherein the ratio of the UV curable urethane or acrylate to silicone acrylate is less than 1:1.
6 . The composition of claim 3 , wherein the fluoropolymer is selected from polytetrafluoroethylene (PTFE) and polyvinylidenefluouride (PVDF).
7 . The composition of claim 1 , comprising from about 1 wt. % to about 40 wt. % of the silicone acrylate.
8 . The composition of claim 3 , wherein the ratio of fluoropolymer to silicone acrylate is about 1:1.
9 . The composition of claim 5 , wherein the coating is substantially free of polyethylene.
10 . The composition of claim 1 , further comprising an abrasive selected from aluminum oxide; silica and a combination thereof.
11 . The composition of claim 3 , comprising:
about 6 wt. % of the UV curable urethane or acrylate having one or more phosphate ester moieties;
about 7 wt. % of the silicone acrylate; and
about 7 wt. % of the fluoropolymer.
12 . The composition of claim 11 , wherein acrylates comprise about 75 wt. % of the composition.
13 . The composition of claim 1 , wherein a coating produced from the composition demonstrates a Δb of less than 10 in a 1-minute iodine test and greater than 90% gloss retention in a Gardner Scratch Test.
14 . A flooring product comprising:
a substrate; and
a surface coating composition comprising:
from about 1 wt % to about 40 wt % of a UV curable urethane or acrylate having one or more phosphate ester moieties;
from about 0.1 wt % to about 40 wt % of a silicone acrylate; and
from about 0.1 wt % to about 40 wt % of a flouropolymer.
15 . The product of claim 14 , wherein the composition is applied at a thickness sufficient to provide a coating having a thickness of from about 5 microns to about 50 microns.
16 . The product of claim 14 , wherein the substrate comprises a plurality of layers.
17 . The product of claim 16 , wherein the substrate comprises a decorative layer; a wear layer; and a backing layer.
18 . The product of claim 17 , wherein the decorative layer and wear layer are combined in single layer.
19 . A heat-exposure resistant coating composition comprising:
from about 1 wt. % to about 40 wt. % of a UV curable curable urethane or acrylate having one or more phosphate ester moieties, and
from about 0.1 wt. % to about 40 wt. % of a silicone acrylate.
20 . The composition of claim 19 , wherein the composition further comprises from about about 0.1 wt. % to about 40 wt. % of a flouoropolymer.
21 . A method of improving the scratch resistance, stain resistance or heat-exposure resistance of a flooring product comprising applying to the major surface of a substrate, the coating composition of claim 1 ; and exposing the coated substrate to at least one radiation source.
