Anhydride epoxy hardeners need to react with epoxy resin and cure under high temperatures. They undergo anhydride-epoxy reactions, requiring high heat for full curing. Depending on the conditions, this resin can be tailored into a cross-linked polymer which offers exceptional electrical insulation. This is perfect for other forms of electrical equipment and electronics, such as transformers and circuit boards. Aside from this, anhydride cured epoxy also offers exceptional resistance against heat, acids, and other harsh chemicals. In addition, anhydride epoxy hardeners are more convenient to work with when applied at room temperatures, thus slow curing processes are advantageous. When fast curing is done at high temperatures, it ensures the structure remains cross-linked, which is important for high-performance applications.
