APPLICATIONS

Diamines are compounds which contain two amino groups. Both aliphatic (linear or branched) diamines with from short carbon chain (from 2) to fatty length and aromatic diamones are used as a monomer to form copolymers like nylons, polyesters and polyurethanes. They can form a protein-like structure at both ends of each monomer. The chain length characteristics with recurring amide groups provide a variety physical properties and are further processed into various applications including plastics, oil-modified and moisture-area types of urethane coatings, polyamides for printing inks, dimer acids, textiles, lubricant additive as scale and corrosion inhibitor, epoxy curing agent, isocyanates, water treatment chemicals, biocides, and pharmaceutical intermediates.

N,N-Dimethyl-1,3-diaminopropane, a short chain aliphatic diamine containing 1° and 3º nitrogen atoms, is used as a polymer cross linkage agent, polyurethane extender and spray coatings. It is used as a chemical intermediate for epoxy curing agents, surfactants, antiseptic agents and other organic chemicals (e.g auxiliary for the paper, textile, and leather industries)
