ABSTRACT:
A flexible mica sheet is made by: (A) mixing solid and liquid epoxide resin in a dual solvent system, (B) adding an organo-titanate catalyst, and mixing to form a homogeneous admixture, (C) applying the admixture to a sheet material comprising mica, so that organo-titanate contacts the mica, causing organo-titanate to act as a latent catalyst, and (D) removing solvent, to form a flexible B staged epoxide resin containing an amount of organo-titanate effective to cure the epoxide in the sheet material heating.
