The Effect of Different Components in Formulation on Properties of Adhesives Based on Epoxy

Epoxy resins can be used as coating or adhesive under different environmental conditions because of high adhesion, good chemical and heat resistance, excellent mechanical properties and very good electrical resistance. Epoxy adhesives have relatively complex formulation of components with unique features. Different components of adhesive formulation are set depending on material of adherents, operating conditions, costs, and required properties. The properties of epoxy adhesives can be improved for diverse applications with the change in the components of the adhesive formulation such as blending epoxy resin with other polymers, choossing appropriate curing agent, adding reinforcements, organic and inorganic fillers, and tougheners. In this paper, various components of epoxy adhesives formulation will be discussed, and their relationship with final properties of adhesives are studied.
