ABSTRACT:
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.
