Abstract
A composition for use as a wood-filler that includes a modified styrene butadiene latex; at least one pH indicator, wherein pH indicator causes the composition to change color as the composition dries; and one or more types of microspheres, wherein the microspheres provide durability and stainability to the wood-filling composition.
Claims8
A composition for use as a wood-filler, consisting of:
- (a) a styrene butadiene latex;
- (b) at least one pH indicator, wherein the at least one pH indicator is operative to provide a visual indication that the composition is dry, and wherein the visual indication is based on a color change of the composition that occurs as the composition dries;
- (c) microspheres, wherein the microspheres include glass or ceramic or both, and wherein the microspheres provide durability and stainability to the wood-filling composition;
- (d) water;
- (e) at least one pH controller;
- (f) at least one surfactant;
- (g) at least one dispersant;
- (h) at least one freeze-thaw stabilizer;
- (i) at least one bactericide;
- (j) at least one defoamer;
- (k) at least one thickener;
- (l) at least one calcium carbonate filler;
- and
- (m) at least one film former.
