TH87633A - Siloxane polymerization in wall panels - Google Patents

Abstract

DC60 xyloxane polymerization was modified using gypsum based slurry including plaster, Class C fly ash, magnesium oxide. And siloxane and water emulsions. This slurry is used in How to make gypsum products that are water resistant That includes siloxane and water emulsion, later combining this slurry with Dry mixes of plaster, magnesium oxide And this Class C. Slurry fly ash was later molded as needed, and the plaster was left and the siloxane polymerization. Products obtained It is useful for making water resistant gypsum panels with a core that includes a matrix that A combination of calcium sulfate dihydrate crystals and silicone resins, where the combined matrix is Spread over it with catalys containing magnesium oxide and fly ash components, Class C. Xyloxane polymerization was improved using gypsum based slurry. Including plaster, Class C fly ash, magnesium oxide And the emulsion of siloxanes and water. This slurry was used in How to make gypsum products that are water resistant That includes siloxane and water emulsion, later combining this slurry with Dry mixes of plaster, magnesium oxide And this Class C. Slurry fly ash was later molded to demand, and the plaster was left and the siloxane polymerization. Products obtained It is useful for making water resistant gypsum panels with a core that includes a matrix that A combination of calcium sulfate dihydrate crystals and silicone resins, where the combined matrix is Spread over them with catalys containing magnesium oxide and components from Class C. fly ash.
