Epoxy
Epoxy polymers are cured to form thermoset resins by either homopolymerization of epoxy groups with themselves, or reaction with curing agents such as anhydrides, amines, and novolacs. Because the curing agent contributes significantly to the cured properties of the resin, this is called

Coupling Agents
agents are applied to the surface of the reinforcement or blended into the resin formulation. A sizing agent used on fiberglass yarns can consist of a mixture of coupling agents, lubricants, and binders.
