Estimating the term…
The present invention relates to a composition, and a method of preparing and using the same. The composition contains at least one water-soluble or water-dispersible polymer or combinations thereof, and one or more filler particles that includes WDP gypsum particles. The WDP gypsum particles are obtained from waste gas-desulphurization plants and have a particles size distribution mean diameter ranging from 13 μm to 500 μm. The composition is particularly useful as a surface coating, a surfacing compound, a sealing compound, an adhesive or a molding composition.
A composition comprising:
A process for preparing a polymer-containing composition comprising combining in any order one or more water-soluble or water-dispersible polymers with filler particles, wherein the filler particles comprise WDP gypsum particles that are obtained from waste-gas desulphurization and have a mean particle diameter ranging from 13 μm to 500 μm as measured by the Fraunhofer diffraction technique.
A process for preparing a surface coating, a surfacing compound, a sealing compound, an adhesive, or a molding composition comprising combining one or more water-soluble or water-dispersible polymers with WDP gypsum particles wherein the WDP gypsum particles are obtained from waste-gas desulphurization and have a mean particle diameter ranging from about 13 μm to 500 μm as measured by the Fraunhofer diffraction technique.
