Aliphatic diamines for high-performance epoxy systems

VESTAMIN® curing agents are used for epoxy resins systems, chain extender for PUR systems and raw material for polyamides.

Aliphatic diamines from the VESTAMIN® range are industry-standard crosslinkers for high-performance epoxy systems. Epoxy coatings are used as primers and intermediate layers because they offer outstanding mechanical, chemical and water resistance. They are extremely durable and have excellent adhesion to a variety of substrates. Typical applications include industrial floorings, marine and anticorrosive paints, as well as high-performance composites.

VESTAMIN® Portfolio

VESTAMIN® IPD is a cycloaliphatic diamine, based on isophorone chemistry. It is a mixture of two stereo-isomers of 3-aminomethyl-3,5,5- trimethylcyclohexylamine, and is a colorless low viscosity liquid with a faint amine odor.

With 50 years of experience in epoxy applications VESTAMIN® IPD is regarded as the state of the art material for the epoxy industry.

VESTAMIN® PACM is a cycloaliphatic diamine which is manufactured by hydrogenation of methylene dianiline. It is a mixture of different isomers, and contains appoximately 20% of the trans, trans-PACM.


  • Industrial floorings
  • Composites
  • Specialty polyamides


  • Low mix viscosity
  • Moderate reactivity
  • Low exothermic behavior
  • Outstanding mechanical properties
  • Excellent chemical resistance

VESTAMIN® A 139 is a liquid, blocked crosslinker for polyisocyanate resins based on a cycloaliphatic diamine. Exhibits a very low reactivity towards isocyanate groups. The crosslinking with polyisocyanate resins occurs under the influence of moisture by releasing the original diamine, which is spontaneously reacting with the isocyanate groups under formation of urea structures.


  • Moisture-curing paint


  • Accelerating effect
