Abstract: Organopolysiloxane release coatings employing a higher molecular weight organopolysiloxane crosslinker having Si—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.

Abstract: Crosslinkable compositions contain (1) organosilicon compounds which have radicals containing aliphatic carbon-carbon multiple bonds (2) organosilicon compounds having Si-bonded hydrogen atoms (3) catalysts which promote the addition of Si-bonded hydrogen onto aliphatic multiple bond and (4) agents which retard the addition of Si-bonded hydrogen onto aliphatic multiple bond at room temperature of the formula CH2?C(R2)—CR1(OH)—R??(I) wherein R is hydrogen or a monovalent hydrocarbon radical having 1 to 12 carbon atoms, optionally substituted with one or more hydroxyl groups, with the proviso that R is not hydrogen if R1 and R are both hydrogen, R1 is hydrogen or a monovalent hydrocarbon radical having 1 to 12 carbon atoms, or R1 together with R form a cyclic hydrocarbon radical having 1 to 12 carbon atoms and R2 is hydrogen or a monovalent hydrocarbon radical having 1 to 12 carbon atoms.

Abstract: 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.

Abstract: Composite structures prepared by laying up a plurality of plies of thermoplastic or thermoset fiber reinforced prepregs are produced by adhering a high parting force consolidation liner on at least one surface of the layup prior to curing and consolidation. The surface coating on the release paper is preferably free of controlled release additives, adheres well to consolidated compositions, and can be removed to expose the composite surface.
