METHOD FOR PRODUCTION OF POLYORGANOSILOXANE VARNISH Russian patent published in 1998 - IPC

Abstract RU 2108347 C1

FIELD: production of film-forming agents, hydrophobic agents and binders for composite materials. SUBSTANCE: varnish is prepared by etherification of methyltrichlorosilane and phenyltrichlorosilane (its quantity being 10-35 mass %) which takes place in aqueous-butanol-xylene solution. Thus obtained hydrogen chloride is removed and products of etherification are treated by special solution. Solution comprises, mas.% hydrogen chloride, 8.0-15.0; butanol, 2.0-6.0; and water, up to 100. EFFECT: improved efficiency of the method. 3 cl, 2 tbl
