Abstract
Official abstract text for this publication.
Water-based stains are based on an oil-in-water emulsion having a binder that includes, consists of, or consists essentially of drying oil combined with a non-aqueous polymer dispersion. The compositions can be tinted using traditional water-based pigment dispersions, yet the overall hydrophobicity results in minimal interaction with the polar cellulosic structure of wood.
First claim
Opening claim text (preview).
What is claimed is: 1. A wood stain composition comprising: a water-based stain in the form of an oil-in-water emulsion, the emulsion comprising a binder consisting essentially of drying oil and a non-aqueous polymer dispersion. 2. The composition of claim 1 , further comprising a water-based pigment dispersion. 3. The composition of claim 1 , wherein the non-aqueous polymer dispersion is an alkyd dispersion. 4. The composition of claim 1 , further comprising a thickener. 5. The composition of claim 4 , wherein the thickener consists essentially of hydroxyethylcellulose, hydrophobically-modified ethylene oxide-based urethanes, or hydrophobically-modified alkali soluble emulsions. 6. The composition of claim 1 , further comprising a defoamer. 7. The composition of claim 1 , further comprising an amine. 8. The composition of claim 7 , wherein the amine consists essentially of dimethylethanolamine, monoethylethanolamine, trimethylethanolamine, morpholine, or ammonia. 9. The composition of claim 1 , further comprising at least one drying agent. 10. The composition of claim 1 , further comprising a surfactant. 11. The composition of claim 10 , wherein the surfactant has a hydrophile-lipophile balance value between 5 and 15. 12. The composition of claim 10 , wherein the surfactant is an octylphenol ethoxylate surfactant. 13. The composition of claim 1 , wherein the drying oil is tung oil.
