SILICON RESIN EMULSION AND USE THEREOF IN HYDROPHOBING PLASTER

摘要

Silicone resin emulsions especially suitable for hydrophobing gypsum compositions together with H-siloxanes are prepared by hydrolysis and subsequent distillation to an alcohol content of less than 0.1 weight percent. Use of the emulsion with H-siloxanes provides plaster products such as plasterboard of increased hydrophobicity.
