Abstract

A stain composition for applying a stain to a wood substrate includes a carbonate ester solvent system, an acrylic resin, a siloxane-containing composition, and an optional pigment composition. The stain composition advantageously has a minimum amount of VOCs.

First claim

What is claimed is:

1. A stain composition comprising:
a carbonate ester solvent system including dimethyl carbonate;
an acrylic resin;
a siloxane-containing composition;
a pigment composition; and
an organoclay suspending agent.

2. The stain composition of claim 1 wherein the organoclay suspending agent is present in an amount from about 0.1 to 2 weight percent of the total weight of the stain composition.

3. The stain composition of claim 1 wherein the carbonate ester solvent system further includes a combination selected from the group consisting of diethyl carbonate, dipropyl carbonate, propylene carbonate, and combinations thereof.

4. The stain composition of claim 1 wherein the carbonate ester solvent system further includes propylene carbonate.

5. The stain composition of claim 1 wherein the acrylic resin includes homopolymers or copolymers of methacrylate, acrylate, methyl methacrylate, methyl acrylate, ethyl methacrylate, ethyl acrylate, n-propyl acrylate, n-propyl methacrylate, iso-propyl methacrylate, iso-propyl acrylate, n-butyl acrylate, n-butyl methacrylate, isobutyl acrylate, isobutyl methacrylate, sec-butyl acrylate, sec-butyl methacrylate, tert-butyl acrylate, tert-butyl methacrylate, tert-amyl methacrylate, n-hexyl acrylate, n-octyl methacrylate, 2-ethylhexyl acrylate, n-decyl methacrylate, iso-decyl acrylate, iso-decyl methacrylate, undecyl methacrylate, n-dodecyl acrylate, n-dodecyl methacrylate, 1-hexadecyl methacrylate, stearyl acrylate, stearyl methacrylate, cyclohexyl acrylate, cyclohexyl methacrylate, 3,3,5-trimethylcyclohexyl methacrylate, isobornyl methacrylate, benzyl acrylate, benzyl methacrylate, pentabromophenyl acrylate, pentabromophenyl methacrylate, pentafluorophenyl acrylate, pentafluorophenyl methacrylate, phenyl acrylate, phenyl methacrylate, 1,1,1,3,3,3-hexafluoroisopropyl acrylate, 1H,1H,2H,2H-heptadecafluorodecyl acrylate, 1H,1H,2H,2H-heptadecafluorodecyl methacrylate, 1H,1H,3H-hexafluorobutyl acrylate, 1H,1H,3H-hexafluorobutyl methacrylate, 1H,1H,3H-tetrafluoropropyl methacrylate, 1H,1H,5H-octafluoropentyl acrylate, 1H,1H,5H-octafluoropentyl methacrylate, 1H,1H,7H-dodecafluoroheptyl methacrylate, 1H,1H-heptafluorobutyl acrylate, 2,2,2-trifluoroethyl acrylate, 2,2,2-trifluoroethyl methacrylate, hexafluoro-iso-propyl methacrylate, pentafluorophenyl acrylate, or pentafluorophenyl methacrylate.

6. The stain composition of claim 1 wherein the acrylic resin includes homopolymers or copolymers of n-butyl acrylate, n-butyl methacrylate, t-butyl acrylate, t-butyl methacrylate, isobutyl acrylate, isobutyl methacrylate, or isobornyl methacrylate.

7. The stain composition of claim 1 wherein the acrylic resin includes polymers or copolymers of methyl methacrylate with n-butyl acrylate, n-butyl methacrylate, t-butyl acrylate, t-butyl methacrylate, isobutyl acrylate, or isobornyl methacrylate.

8. The stain composition of claim 1 wherein the siloxane-containing composition includes a silicone.

9. The stain composition of claim 1 wherein the siloxane-containing composition includes a mixture of a silane and a siloxane.

10. The stain composition of claim 9 wherein the mixture further includes a fluoropolymer.

11. The stain composition of claim 9 wherein the silane is an alkoxy silane.

12. The stain composition of claim 11 wherein the silane is an alkoxy silane having the following formula:
(R′O) n R″ 4-n Si

where n is 1, 2, or 3;
R′ is a C 1-4 alkyl group; and
R″ is a C 1-18 alkyl group.

13. The stain composition of claim 11 wherein the alkoxy silane has formula C 16 H 33 Si(OCH 3 ) 3 .

14. The stain composition of claim 1 wherein dimethyl carbonate is present in an amount from about 40 to 80 weight percent of the total weight of the stain composition and propylene carbonate is present in an amount from about 5 to 40 weight percent of the total weight of the stain composition.

15. The stain composition of claim 14 wherein the acrylic resin is present in an amount from about 0.5 to 15 weight percent of the total weight of the stain composition.

16. The stain composition of claim 1 further comprising a mildewcide.

17. The stain composition of claim 1 further comprising mineral spirits.

18. The stain composition of claim 1 wherein the pigment composition is solvent acrylic-based colorant.

19. The stain composition of claim 1 further comprising an additive selected from the group consisting of rheology modifiers, surfactants, defoamers, organic solvents, dispersants, coalescents, light stabilizer, preservatives and combinations thereof.

20. The stain composition of claim 19 wherein the additive is a hindered amine light stabilizer.

21. The stain composition of claim 1 further comprising a fluorinated silane.

22. The stain composition of claim 1 further comprising hexadecyl silane.
