Patent number: 5723521Abstract: Solventless silicone resins, which exhibit a high degree of reconstitution, are produced in forms such as powders and flakes. The degree of reconstitution is judged by the fact that silicone resin/fluid alloys produced therefrom exhibit only a minor shift in T.sub.g, the glass transition temperature, in comparison to analogous alloys produced from solvent dispersed (virgin) resin. Resin, and preferably virgin resin, is dispersed in a volatile liquid dispersant and blended with a nonvolatile silicone fluid. Thereafter, the volatile liquid dispersant is removed by means such as spray-drying or evaporation, resulting in the solventless resin forms of the invention.Type: GrantFiled: July 3, 1995Date of Patent: March 3, 1998Assignee: Dow Corning CorporationInventors: Leon Neal Cook, Richard Allen Hessick, Jr., Hongxi Zhang, Randall Gene Schmidt
