    摘要: The present invention relates generally to wall repair compounds such as joint compounds, spackling compounds, and the like used to repair imperfections in walls or fill joints between adjacent wallboard panels. Particularly, the present invention relates to such a wall repair compound that comprises a dust-reduction additive that reduces the quantity of airborne dust generated when the hardened compound is sanded. The dust-reduction additive also synergistically imparts water resistance and adhesion to the wall repair compounds to which it is added. More specifically, in one embodiment, the dust-reduction additive is an emulsion comprising colloidally-protected, wax-based microstructures comprising paraffin that is chemically encapsulated by polyvinyl alcohol.
