PROCESS FOR THE BODY-HYDROPHOBIZATION OF BUILDING MATERIALS COMPRISING SOLID ORGANOSILICON COMPOUNDS

摘要

Body-hydrophobing of mineral building compositions prepared from water curable mineral materials such as cement and plaster are obtained by admixing into the curable composition an organosilicon compound prepared by reacting a hydrocarbylhalosilane or hydrocarbylhydrocarbyloxysilane with a gylcol or polyglycol in a mol ratio of halo or hydrocarbyloxy radicals to hydroxyl radicals of 0.3 to 1.3. The organosilicon compounds are solid at 20° C.
