LIQUID ORGANOSILOXANE RESIN COMPOSITIONS Abstract This invention provides liquid coating compositions comprising (a) a film-forming component comprising at least one organosiloxane block copolymer wherein the molar ratio of phenylsiloxane units to other units present in the block copolymer is greater than 9.35 to 1, and (b) a solvent comprising at least 45% by weight of a cyclic polydimethylsiloxane of the formula [(CH3)2SiO]x where the average value of x is from 3 to 8 and where said organosiloxane block copolymer constitutes no more than 60% of the combined weight of the copolymer and solvent. Using the present compositions, relatively thin coatings of the block copolymer can be applied to cured polyorganosiloxane elastomers and a variety of synthetic organic polymers.
