Color-changing wood filler

摘要

A composition for use as a wood-filter 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; one or more types of microspheres, wherein the microspheres provide durability and stainability to the wood-filling composition; and high-density polyethylene fibers.

主权项

1. 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 comprise glass or ceramic or both, and wherein the microspheres provide durability and stainability to the composition; (d) at least one slump resister comprising high-density polyethylene fibers; (e) water; (f) at least one pH controller; (g) at least one surfactant; (h) at least one dispersant; (i) at least one freeze-thaw stabilizer; (j) at least one bactericide; (k) at least one defoamer; (l) at least one thickener; (m) at least one calcium carbonate filler; and (n) at least one film former.
