An asphalt composition having a low VOC content composed of an asphalt material; a volatile methylated siloxane from the group of linear methylated siloxane, cyclic methylated siloxane, branched methylated siloxane and any mixtures thereof and fillers, additives organic VOC solvents conventionally used in such a composition, wherein the composition has a VOC level that allows the composition to be used in venues having restricted low levels of VOC.

Low VOC asphalt composition

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.

Low-dust products using a wax emulsion

This disclosure describes formulations and methods for dust control, for example, coal topping, a term which refers to the application of liquid products to the top of coal loads, such as those in open topped coal hopper railcars as commonly used today to transport coal. Disclosed herein are asphalt-based emulsion formulations that accomplish dust control during industrial operations in which dust handling is required.

Asphalt-based dust control formulations

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.

Phase-change materials from wax-based colloidal dispersions and their process of making

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 reduction additive that reduces the quantity of airborne dust generated when the hardened compound is sanded and also exhibits improved adhesive properties. The dust reduction additive also imparts adhesion to the wall repair compounds to which it is added, for example to a joint compound. The dust reduction additive is a powder prepared from colloidally-protected, wax-based microstructure dispersions.

Low dust additives comprising emulsified powder for joint compounds and joint compounds thereof

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.

Low-dust products using microcrystalline wax emulsion

This invention relates to colloidally-protected, wax-based microstructures and dispersions thereof. More specifically, this invention relates to powders prepared from colloidally-protected, wax-based microstructure dispersions and process of making such powders. This invention also relates to a various end-use compositions comprising such powders from wax-based colloidal dispersions.

Powders from wax-based colloidal dispersions and their process of making

Embodiments of the present disclosure are directed to joint compounds for sealing exterior sheathing wallboards applied on the exterior of buildings. This invention also relates to a process of preparing such exterior joint compounds. The joint compounds of this invention comprise an aqueous emulsion system and provide water resistance comparable to the substrate on which they are applied, that is, the exterior sheathing wallboards.

Water-resistant exterior joint compounds

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 reduction additive that reduces the quantity of airborne dust generated when the hardened compound is sanded and also exhibits improved adhesive properties. The dust reduction additive also imparts adhesion to the wall repair compounds to which it is added, for example to a joint compound. The dust reduction additive comprises micro-crystalline wax or micro-crystalline wax emulsion.

Dust control formulations

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 reduction additive (DRA) that reduces the quantity of airborne dust generated when the hardened compound is sanded. The dust reduction additive also imparts adhesion to the wall repair compounds to which it is added, for example to a joint compound. More specifically, this dust reduction additive is of sufficiently lighter shade to not impact the shade of the joint compound upon addition. In one embodiment, this invention relates to a non-foaming dust reduction additive that comprises paraffin and/or micro-crystalline wax-based emulsion.
