UNITARY REACTION RESIN SYSTEMS

摘要

A unitary reaction resin system that is stable in storage and yet cures well consists of a mixture of commercially available epoxy resins and phosphorus-containing glycidyl esters, in particular phosphonic acid diglycidyl esters, and of cationic photo initiators. The low-viscosity reaction resin systems are not curable by purely thermal means and can be processed at high temperatures and in particular be highly filled. The reaction resin systems, which are also stable in storage after UV activation, can under moderate conditions be cured into flame-resistant molding materials.
