  • Gellation process for silicone varnish resins
    Patent number: 5274066
    Abstract: A process for the gelling of a silicone varnish comprises reacting the silicone varnish with an organic coupling agent, preferably an organometallic coupling agent under conditions which are effective and to provide a gel. This gel has a viscosity which is effective for suspending high density particles in the resin without settling of the particles during subsequent processing such as spraying, casting, and/or curing processes. The silicone varnish contains hydroxyl substituents, and is preferably a polyhydroxy substituted silicone varnish, i.e., silanols.
