It is often advantageous to prepare adduct of the epoxy resin and the amine hardener. In effect, this procedure lowers the toxicity and volatility of the unmodified amine, but the reaction is highly exothermic. To control the latter, "Piccolastic" A5 may be used with a small portion of the solvent to cool the reaction. |
