Abstract:
1. An organosiloxane polymer composition, consisting of an organosiloxane polymer formed by a partially cross-linked siloxane backbone comprising residues derived from tri- or tetraalkoxysilane monomers or combinations thereof, said residues making up at least 50 mole-% of the siloxane backbone and at least 70 mole-% of the residues being derived from tetraalkoxysilane monomers; and an essentially non-aqueous solvent mixture comprising a first organic solvent and a second organic solvent, wherein the first organic solvent is an organic compound having hydroxyl groups, wherein the second organic solvent is selected from the group consisting of aliphatic and aromatic hydrocarbons, aliphatic and aromatic ethers, aliphatic and aromatic esters, and mixtures thereof, wherein the second solvent comprises 70 mole-% to 25 mole-% of the solvent mixture, and wherein at least 30 mole-% of the solvent mixture comprises the organic hydroxyl compound.
