  • Publication number: 20250137268
    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.

  • Publication number: 20250100942
    Abstract: A joint compound system includes a drying type ready mix joint compound and a gas generation ingredient added to the ready mix joint compound just prior to use. In some aspects, the gas generation ingredient includes sodium percarbonate. In an aspect, the formulation includes a peroxide stabilizer. The peroxide stabilizer can include sodium silicate. The use of the gas generation ingredient and peroxide stabilizer create an extended period of gas generation, leading to an expansion of the mix joint compound during application, which reduces shrinkage after application, and eliminates the needs for multiple coatings.

  • Patent number: 11312117
    Abstract: This invention generally relates to phase-change materials (“PCM” or “PCM materials”) made from colloidally-protected wax-based microstructures. This invention also relates to such PCM materials configured in various physical forms. This invention further relates to a process of configuring such PCM materials for a variety of end-use applications in which dampening of temperature fluctuations by absorption and desorption of heat is desired. This invention further relates to preparing colloidally-protected wax-based microstructures in particulate form that function as PCM materials.
