'Acrylic weld' of a silicone release composition comprising a polydiorganosiloxane containing unsaturated groups, a crosslinking agent containing Si--H groups and a hydrosilation catalyst is inhibited by incorporating therein at least one free radical inhibitor. The preferred inhibitors are alkoxyphenols, especially 4-methoxyphenol.

Silicone release coating compositions

Shelf stable heat curable mixtures of vinyl substituted organopolysiloxane fluid and siloxane hydride are provided. The one part polyorganosiloxane mixtures are catalyzed with an inclusion compound of a cyclodextrin and a complexing ligand such as, cyclopentadiene, 1,5-cyclooctadiene or norbornadiene and a platinum metal material, such as a C.sub.(1-4) alkyl substituted platinum.

One part heat curable organopolysiloxane compositions

Shelf stable heat curable mixtures of vinyl substituted organopolysiloxane fluid and siloxane hydride are provided. The one part polyorganosiloxane mixtures are catalyzed with an inclusion compound of a cyclodextrin and a complex of a cyclopentadiene, 1,5-cyclooctadiene or norbornadiene and a platinum group metal material, such as a C.sub.(1-4) alkyl substituted platinum or a rhodium halide.
