More Information
Summary:A curable composition contains: (a) 15 to 73 weight-percent of a vinyl functional M-capped aryl silsesquioxane resin: (b) 0.5 to 5 weight-percent of a vinyl functional disiloxane: (c) 2 to 25 wt % of a silicon-hydride functional M-capped silsesquioxane resin; and (d) 1 to 10 weight parts per million weight parts of platinum from a platinum hydrosilylation catalyst: wherein the sum of the concentration of (a) and (b) is at least 35 weight-percent: weight-percent values are relative to weight of curable composition; and the curable composition is free of acetylenic alcohol hydrosilylation inhibitors.
