ABSTRACT:
Curable organosilicone resin coating compositions are disclosed wherein part or all of the solvent ordinarily present in conjunction with a conventional hydroxyl functional organosiloxane resin copolymer is replaced with a reactive liquid silicone resin having an increased flash point and reduced volatility relative to a prior art reactive diluent. The liquid silicone resin employed is a reaction product prepared by hydrolyzing, and the neutralizing, an equilibrated mixture of (i) a phenylsilane and (ii) a polydimethylsiloxane, the equilibration reaction being facilitated by a perfluoroalkane sulfonic acid (iii).
