Composition and method for inhibiting stain formation in a floor covering

1. A composition for inhibiting stain formation in a floor covering, comprising:

a copper glycine complex present in an amount from about 5 to about 20 percent by weight based on the total weight of the composition;

magnesium hydroxide; and

a carrier;

wherein a drying period is not required after

application of the composition to a wood-based substrate, prior to installation of the floor covering.

2. The composition of claim 1 , wherein magnesium hydroxide is present in an amount from about 1 to about 15 percent by weight based on the total weight of the composition.

3. The composition of claim 1 , wherein the copper glycine complex has a copper to glycine molar ratio in the range of from about 1:1 to about 1:4.

4. The composition of claim 1 , wherein the carrier is substantially insoluble in polyvinyichioride-based plastisols.

5. The composition of claim 1 , wherein the carrier comprises an aromatic polyether-based polyol.

6. The composition of claim 1 , wherein the carrier is present in an amount from about 20 to 80 percent by weight of the total composition.

7. The composition of claim 1 further comprising an additive, wherein the additive is at least one of an opacifying agent, a viscosifying agent, a diluent, a polymer, a surfactant, a dispersant, a filler, a preservative, or a colored pigment.

8. The composition of claim 7 , wherein the opacifying agent comprises titanium dioxide.

9. The composition of claim 7 , wherein the viscosifying agent is at least one of fumed silica or an associative thickener.

10. The composition of claim 7 , wherein the surfactant comprises a nonionic surfactant.

11. The composition of claim 7 , wherein the polymer comprises a carboxylated styrene-butadiene latex.

12. The composition of claim 1 , wherein the composition includes dispersed particles up to about 5 um in size.

13. A method for inhibiting stain composition in a floor covering overlaying a wood-based substrate, comprising:

a) applying a stain inhibiting composition to a surface of a wood-based substrate to provide a coated wood-based substrate, wherein the composition comprises a copper glycine complex present in an amount from about 5 to about 20 percent by weight based on the total weight of the composition, magnesium hydroxide, and a carrier, wherein a drying period is not required after application of the composition to the wood-based substrate, prior to installation of the floor covering; and

b) overlaying the floor covering onto the coated wood-based substrate.

14. The method of claim 13 , wherein the floor covering comprises a vinyl floor covering.

15. The method of claim 13 , wherein the wood-based substrate comprises oriented strandboard.

16. The method of claim 13 , wherein the composition is applied by spraying.

17. The method of claim 13 , wherein the composition is applied by roll coating.

18. The method of claim 13 , wherein the floor covering is overlaid onto the wood-based substrate immediately after coating the stain inhibiting composition onto the substrate.

19. A flooring assembly resistant to stain formation, comprising:

a floor covering; and

a wood-based substrate having a surface coated with a composition for inhibiting stain formation in the floor covering, the composition intermediate the wood based substrate and the floor covering, wherein the composition comprises:

a copper glycine complex present in an amount from about 5 to about 20 percent by weight based on the total weight of the composition;

magnesium hydroxide; and

a carrier;

wherein a drying period is not required after application of the composition to the wood-based substrate, prior to installation of the floor covering.

20. The flooring assembly of claim 19 , wherein the wood-based substrate comprises oriented strandboard.

21. The flooring assembly of claim 19 , wherein the floor covering is a vinyl floor covering.

22. The flooring assembly of claim 19 , wherein the flooring assembly is installed in a manufactured home.
