APPLICATIONS

Diamines are compounds which contain two amino groups. Both aliphatic (linear or branched from short C-2 chain to fatty length ) and aromatic diamines are used as a monomer to form copolymers like nylons, polyesters and polyurethanes for characteristic properties. 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.

Diethylaminopropylamine, aliphatic diamine, is used as a polymer cross linckage agent, polyurethane extender and spray coatings. It is used as a chemical intermediate for epoxy curing agents, pharmaceuticals, agrochemicals, and other organic chemicals (e.g auxiliary for the paper, textile, and leather industries). Common aliphatic amine class curing agents include:

  • Diethylenetriamine (CAS RN: 111-40-0)
  • Trientine (CAS RN: 112-24-3)
  • N,N-Diethyltrimethylenediamine (CAS RN: 104-78-9)
  • Menthane diamine (CAS RN: 80-52-4)
  • Aminoethylpiperazine (CAS RN: 140-31-8)
  • 1,3-Xylenediamine (CAS RN: 1477-55-0)
  • Isophorone diamine (CAS RN: 2855-13-2)
