Wasserabstossende Organosiliciumzusammensetzungen

摘要

A composition in the form of an aqueous solution made by combining (i) an alkyltrialkoxysilane with C1 to C10 alkyl groups on silicon; (ii) a silane coupling agent which is an amino organofunctional trialkoxysilane or a quaternary ammonium organofunctional trialkoxysilane; (iii) a blend of petroleum and synthetic hydrocarbon waxes; and (iv) an aqueous silicone resin emulsion. The composition is used in the treatment of cellulosic and masonry surfaces to render the surface water repellent.
