Storage stable epoxy resin compositions for electrical laminates

United States Patent(美国专利号):8980376

Abstract:Epoxy resin compositions that include an epoxy resin component that includes at least one epoxy resin and a solvent blend that includes methyl ethyl ketone and glycol methyl ether acetate are provided. The compositions are well-suited for use in the fabrication of prepregs and composite electrical laminates made therefrom.

Background:Low viscosity mixtures of solvents and epoxy resins are used in the manufacture of electrical laminates. Unfortunately, some higher functional epoxies and highly brominated epoxies that are desirable for use in such mixtures are difficult to solubilize and, therefore, do not maintain solubility over long periods of time. This makes it difficult to manufacture, store, and ship resin solutions that include these types of epoxies.
