Formulating Tips for Epoxy-Anhydride Cure Systems

Join this webinar to learn the basics of epoxy-anhydride curing systems, and how pairings of accelerators and anhydrides can achieve desired processing/property relationships.

Epoxy resins have been cured thermally with anhydrides since the 1960s. Retention of physical, mechanical and electrical properties under high-temperature conditions has been the hallmark of this technology. Where the chemistry is well-known, these systems are confidently used in practice daily, in specialty applications including electronic coating powders and encapsulants. However, more recent demands have been placed on the epoxy-anhydride pairing, where established performance is being challenged by lower curing temperatures, shorter curing cycles, and an overall desire to expand their use beyond traditional molding compounds into adhesives, composites and coatings for not only for industrial electronics but now in rapidly expanding applications for automotive and infrastructure. These challenges require a greater understanding of resins, anhydrides and accelerators to achieve optimal properties. Most of this information has been historically based on empirical knowledge and trial-and-error combinations of components. In this webinar, we will take an in-depth look at these variables in order to provide a greater awareness of formulating options for professionals from the bench top to the production floor. In some cases, default formulations were improved dramatically, resulting in greater degrees of cure, higher glass transition temperatures, lower curing temperatures and faster curing cycles. We offer these results to spark further discussion and encourage wider use of this established yet highly relevant technology.
