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.

Low temperature cure silicone release coatings

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.
