Abstract: Wax emulsions for the manufacture of wallboard include water; a lignosulfonic acid or a salt thereof; and at least one wax selected from the group consisting of slack wax, paraffin wax and montan wax. The emulsions may have a pH of between about 6.5 and 7.9. Such emulsions can provide enhanced moisture resistance to the wallboard.

Abstract: A joint compound or wall repair composition and the method of making the same is disclosed that reduces the amount of airborne dust emitted during traditional sanding processes. Generally, such a reduction can be achieved by combining a first binder that has a high glass transition temperature and a second binder that has a low glass transition temperature with conventional joint compound compositions.

Abstract: 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 comprising a dust reducing additive that reduces the quantity of airborne dust generated when the hardened compound is sanded. The dust reducing additive also imparts adhesion to the wall repair compounds to which it is added, for example to a joint compound. The dust reducing additive comprises microcrystalline-wax based emulsion.

Abstract: 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.

Abstract: This invention generally relates to phase-change materials (PCM) comprising colloidally-protected wax-based microstructures and optionally, an absorbent material such as activated carbon. This invention also relates to such PCMs configured in various physical forms. This invention further relates to a process of configuring such PCMs for a variety of end-use applications in which dampening of temperature fluctuations by absorption and desorption of heat is desired. This invention also relates to PCM with reduced leaking of paraffin from the CPWB microstructures. This invention further relates to preparing colloidally-protected wax-based microstructures in particulate form that function as PCMs.
