High energy electron beam curing of epoxy resin systems incorporating cationic photoinitiators

Patent Janke, Christopher J [Powell, TN]; Lopata, Vincent J [Manitoba, CA]; Havens, Stephen J [Knoxville, TN]; ...

A mixture of epoxy resins such as a semi-solid triglycidyl ether of tris (hydroxyphenyl) methane and a low viscosity bisphenol A glycidyl ether and a cationic photoinitiator such as a diaryliodonium salt is cured by irradiating with a dosage of electron beams from about 50 to about 150 kGy, forming a cross-linked epoxy resin polymer.

Use of 2,5-dimethyl-2,5-hexane diamine as a curing agent for epoxy resins

Patent Rinde, James A. [Livermore, CA]; Newey, Herbert A. [Lafayette, CA]

Primary diamines of the formula ##STR1## wherein R is a straight chain saturated hydrocarbon of 2 to 4 carbons, a disubstituted benzene ring, or disubstituted dibenzo methane for use as a curing agent for epoxy resins. These curing agents can be used to form epoxy resin mixtures useful in filament winding and pre-impregnated fiber molding and in formulating film adhesives, powder coatings and molding powders. The epoxy mixtures form for such uses as room temperature non-reacting, intermediate stable state which has a latent cross-linking capability.
