ISOPHORONE DIAMINE

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.

Cycloaliphatic diamines are used in urethane and epoxy coatings for light-stable, weather-resistant properties. It is used in water proofing and paving concreting. It is used in manufacturing diisocyanates and polyamides. Common cycloaliphatic diamines include isophorone diamine, 1,2-diaminocyclohexane, 1,4-bis(aminocyclohexyl)methane, 1,3-bis(aminomethyl)cyclohexane, bis(aminomethyl)norbornane. They are versatile intermediate to produce leather, rubber products, plastics, pesticides, dyes, and photo sensitive polymers. It is used in manufacturing diisocyanates and polyamides. Aliphatic diamines are the most common epoxy curing agent. Members include:
