Anhydride Curing & Thermal Stability

Formulating epoxy resin systems with anhydrides can offer great advantages such as long pot life, low viscosity, excellent thermal stability, high Tg’s and low shrinkage. However, curing with anhydrides can also be very challenging as they require significant heat input to initiate the polymer reaction.

Have you ever asked the question: “Why does the recommended blend ratio include excess epoxide?”

Epoxy formulators often incorporate anhydride curatives into their resin formulations for their ability to provide higher Tg values. It is important when formulating any polymer reaction to take into consideration potential competing reactions.
