Extended amine curing agents and epoxy resins cured therewith

摘要

A method for curing 1,2-epoxy resins wherein a 1,2-epoxy resin is mixed with an effective amount of an amine curing agent comprising a solution of a normally solid cured polyurethane elastomer in a 1,2-epoxy-interactive polyamine curing agent, whereby reaction of the amino hydrogens of the said polyamine with the epoxy groups in the epoxy resin will result in curing of the epoxy resin.
