Abstract

A wood stain composition comprises or consists essentially of a water-miscible polyol having a molecular weight less than 1000 Da, a water-dispersible hydrophobic polymer and a pigment dispersion for providing improved application properties and compliance with regulatory VOC limits.

First claim

What is claimed is:

1. A wood stain composition consisting essentially of:
a water-miscible polyol having a molecular weight less than 1000 Da;
a water-dispersible hydrophobic polymer; and
a pigment dispersion.

2. The composition of claim 1 , wherein the water-miscible polyol is polyethylene glycol.

3. The composition of claim 2 , wherein the polyethylene glycol has a molecular weight of 600 Da±10%.

4. The composition of claim 1 , wherein the water-dispersible hydrophobic polymer is a polyurethane dispersion, a polyester dispersion, an acrylic dispersion or an alkyd dispersion.

5. The composition of claim 4 , wherein the polyurethane dispersion consists essentially of a one-component, self cross-linking polyurethane dispersion.
