Organopolysiloxane for use in release coating compositions are modified to control release values by substitution with phenolic compounds.

Silicone release coating compositions

There is provided a curable substantially uniform mixture of an epoxy silicone, polyarylonium salts and a compatibilizer in the form a mixture of a long chain alkyl substituted phenol and an alkane diol. The curable mixture is convertable to a non-toxic, tack free adherent release coating for pressure sensitive adhesives.

UV curable non-toxic epoxysilicone release coating compositions

A method is provided for enhancing the controlled release characteristics of paper or plastic substrates by applying onto the substrate, a UV curable mixture of an epoxysilicone, an arylonium salt catalyst, such as a diaryliodoniumhexafluoroantimonate and a controlled release additive such as a phenolpropyl-substituted methyldisiloxane or an alkylphenol, such as dodecylphenol. The treated plastic or paper substrate is then subjected to UV irradiation to effect a tack-free cure of the UV curable mixture on the substrate.
