Abstract

Adducts are prepared from partially hydrolyzed epoxy resins having an average functionality of at least about 2.6 such as a partially hydrolyzed phenol-formaldehyde epoxy novolac resin and a polyamine such as diethylenetriamine. These adducts are useful in preparing low temperature curable epoxy resin compositions.
