ABSTRACT:
The invention is an epoxy resin composition. Diol initiators are reacted with alkylene oxide and 1 to 5 wt % epoxy resin. The epoxy resin is added internally, along the length of the diol chain to yield a modified polyol of molecular weight 2000 to 5000. The modified polyol is subjected to reductive amination to yield a polyamine. This polyamine is mixed with an epoxy base resin and cured to product epoxy resins demonstrating improved strength and adhesion.
