Epoxy Curing Agents and Modifiers
Ancamine 2678 curing agent is designed for use as a curing agent for liquid epoxy resins with similar performance to AEP in most applications. It is characterized by its rapid gel at room temperature to give a B-state cure.
It requires an elevated temperature post-cure to obtain optimum properties, notably high impact strength and good thermal shock resistance. It can also be formulated with flexibilizers, plasticizers, and other amines to give systems that will cure at room temperature.
