Catalysts.

摘要

A platinum catalyst which comprises the admixture 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 or Si-OH. They are valuable in producing cured organopolysiloxanes such as release coatings.

They are characterised by storage stability and freedom from corrosion of metallic containers.
