TETA as an Epoxy Hardener
Triethylenetetramine is a widely used epoxy hardener, particularly where ambient cure speed, chemical resistance, and adhesion to metal substrates are required. TETA-cured epoxies are used in protective coatings for pipelines, structural steel, and concrete. As a chemical intermediate, TETA is the basis for polyamide hardeners produced by reacting it with dimer fatty acids, yielding flexible, blush-resistant curing agents.
供應與安全
TETA is a corrosive and sensitizing liquid. Terracore supplies in 200 L steel drums with full SDS and COA. Amine value, colour, and viscosity data are reported on the COA. Skin sensitization hazard declarations are included in the SDS for formulator compliance.
