PLATINUM CATALYST FOR ORGANOSILICON COMPOUNDS

摘要

A platinum catalyst which comprises the admixture of of (a) a haloplatinum compound (b) an aliphatically unsaturated organosiloxane compound and (c) an aluminium alkoxide. These catalysts give high activity in promoting reactions of Si-H compounds with unsaturated groups of Si-OH. They are valuable in producing cured organopolysiloxanes such as release coatings. They are characterized by storage stability and freedom from corrosion of metallic containers.
