Classification of hardening agents used for epoxy resin adhesives.

Classification	Features
Polyamine type hardening agents	Aliphatic polyamine: the reaction is fast and heat generation is remarkable. Durable to water and organic solvent. Good adhesion.
	Aliphatic polyamine: the reaction is fast and heat generation is remarkable. Durable to water and organic solvent. Good adhesion.
	Polyamide: long pot life and low cost
	Epoxy-adducted polyamine: high viscosity (useful to viscosity control).
	Mannich-modified polyamine: good to low-temperature hardening.
	Polythiol: good to low-temperature hardening polymer network structures are looser than those of polyamine. High water adsorption. Low durability to water.
Catalysts	Tertiary amine: catalyst of polyamine and as catalysts of polyamine and polyamide amine.
	Imidazole: reacts as hardening agents and as catalysts of anhydride hardening agents.
