Abstract

A process for preparing adhesive repellent coatings which comprises applying to the surface to be rendered adhesive repellent a mixture containing (1) a diorganopolysiloxane having an Si-bonded vinyl group in each of the terminal units, but is otherwise free of aliphatic unsaturation, (2) an organopolysiloxane having at least 3 Si-bonded hydrogen atoms per molecule, (3) a vinylsiloxane platinum complex and (4) an organic or organosilicon compound which retards or delays the addition of Si-bonded hydrogen to aliphatic multiple bonds, said compound has a boiling point of at least 25.degree. C. at 760 mm Hg (absolute) and at least one aliphatic triple bond, and thereafter crosslinking the diorganopolysiloxane (1).
