Curable resin mixtures and means of curable resin compositions based on prepolymer polyetherurethanurinstofaminer and epoxy resins

摘要

The method of hardening a glycidyl compound with a polyether urethane urea amino hardener is disclosed, said hardener being prepared by reacting (1) a blocked prepolymer prepared by reacting a phenolic compound with the reaction product of a polyether polyol with an excess of polyisocyanate, with (2) a polyfunctional amino compound.
