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.
