Title: Halogen free benzoxazine based curable compositions for high T.sub.g applications

Patent ·
OSTI ID:1298003

A method for forming a halogen-free curable composition containing a benzoxazine monomer, at least one epoxy resin, a catalyst, a toughening agent and a solvent. The halogen-free curable composition is especially suited for use in automobile and aerospace applications since the composition, upon curing, produces a composite having a high glass transition temperature.
