Industrial Applications

Epoxy Curing Agents

Primary curing agent for epoxy resins in coatings, adhesives, and composites. Reacts with epoxide groups to form cross-linked thermoset networks.

Chelating Agents

Feedstock for EDTA and other polyaminocarboxylic acid chelating agents used in water treatment, cleaning, and agriculture.

Fuel Additives

Corrosion inhibitor and lubricity additive in fuel systems. DETA-based imidazolines protect metal surfaces in oil and gas applications.

Paper & Textile

Wet-strength resin intermediate and textile softener. Reacts with epichlorohydrin to form polyamidoamine-epichlorohydrin (PAE) resins.

Asphalt Additives

Adhesion promoter in asphalt emulsions and anti-stripping agents for road construction and maintenance.

Chemical Synthesis

Intermediate for imidazolines, amidoamines, and polyamine derivatives used across industrial and specialty chemical markets.
