Organopolysiloxane release coatings employing a higher molecular weight organopolysiloxane crosslinker having Si&#x2014;H groups on not more than 67 mol percent of all siloxy groups of the organopolysiloxane crosslinker, and a lower molecular weight aliphatically unsaturated organopolysiloxane, cured by hydrosilylation with a hydrosilylation catalyst, produce strongly anchored release coatings which are able to be cured for shorter times and/or lower temperatures, and still offer a lower level of extractables than advanced release coatings employing precrosslinked unsaturated silicones.

Crosslinkable compositions

Baking papers suitable for a wide range of baked goods have a non-stick coating prepared by coating a suitable substrate with an aqueous coating composition comprising an EVA copolymer dispersion and a hydrosilylation curing silicone emulsion, wherein the EVA copolymer dispersion has an EVA copolymer particle size of less than 500 nm and is surfactant-stabilized.

Water-in-oil invert emulsions containing no surfactant are formed by simple mixing of water with organopolysiloxanes containing all of aralkyl, long chain alkyl, and hydrophilic groups. The surfactant-free water-in-oil invert emulsions have a wide variety of uses, for example in compositions for surface care, antifog coating compositions, cosmetic compositions, and hair care compositions.
