Abstract
The disclosure relates to solving problems associated with conventional latent epoxy curing agents by providing a new class of latent epoxy curing agents. In particular, the disclosure relates to epoxy curing agents with improved storage stability and low use level (e.g., less than about 10 wt % relative to the epoxy compound) by forming solid solutions of certain classes of amines in polyphenolic resins.
