Abstract
Provided is a release coating composition including a combination of branched polyorganosiloxanes. The first branched siloxane in the combination is an MDQ siloxane of unit formula: (RSiO)(RRSiO)(RSiO)(SiO), a≥0, b>0, c≤995, and d>0. The second branched siloxane in the combination is an MDT silsesquioxane of unit formula: (RSiO)(RRSiO)(RSiO)(RSiO), e≥0, f>0, g≤995, and h>0. Each Ris independently a monovalent hydrocarbon group free of aliphatic unsaturation and each Ris an aliphatically unsaturated hydrocarbon group. The release coating composition further includes a crosslinker having at least 3 silicon-bonded hydrogen atoms per molecule, a platinum group metal catalyst and an inhibitor.
