Organo-titanate gellation of epoxy resin coated articles
An article, such as a mica wrapped coil, a dynamo-electric machine component containing mica wrapped coils, or a metal substrate, is insulated by: (A) applying wet epoxy resin to the article, (B) contacting the wet epoxy resin with a titanate solution, for a time effective to form a resin impervious, gelled epoxy skin on the surface of the epoxy resin, where the titanate solution consists essentially of organo-titanate and an organic, non-polar solvent, where the weight ratio of organo-titanate:organic non-polar solvent is from 1:2.5 to 1:99, and (C) curing the epoxy resin.
