Its properties make 1, 2-Diaminocyclohexane suitable for a wide range of industrial applications with epoxy resins. The resulting coatings show

  • Excellent resistance to blush.
  • High resistance to chemicals, staining and moisture uptake.
  • Effective at low addition levels giving good commercial advantages in formulation.
  • Its low equivalent weight gives a higher curing capacity on a weight basis.
  • Low viscosity allows for easier application and gives a coating with better levelling, flow and smoothness.


1, 2-Diaminocyclohexane has use as a curing agent in a wide range of industrial applications where high resistance properties are needed such as floor coatings, marine coatings and a number of industrial coatings where high chemical resistance is needed.

You may also use it as a chain extender in pre-polymer or two stage production of some polyurethane resins, as it has a direct influence on the distribution of hard/soft elements in the polymer. It also affects the degree of crystallinity of the resultant polyurethane.

Some acid derivatives of 1, 2-diaminocyclohexane can be used in a range of water treatments such as chelation and flocculation, with specific acid derivatives finding use as speciality flocculating agents in pulp.

The crosslinking ability can find application as a modifier in certain construction products such as PU and epoxy adhesives, and certain carbon-fibre composites.

It is also used in Oxaliplatin, a platinum-based antineoplastic agent used in cancer chemotherapy.
