Diamines VESTAMIN®

Evonik is one of the leading suppliers of high-performance crosslinkers to the composite industry. Evonik crosslinkers play an important role in a majority of advanced composite applications.


VESTAMIN® IPD, a cycloaliphatic diamine, is regarded as the industry standard for crosslinkers and is formulated for epoxy composite systems.

The cycloaliphatic structure and medium reactive amino groups offer the following advantages:

  • good processability of the liquid matrix system
  • high-performance composites with high glass transition temperatures
  • high mechanical strength
  • improved mechanical properties
  • good temperature performance
  • resistance to impact stress
  • moisture and hot-water resistance
  • good chemical resistance.

Typical applications are fiber-reinforced composites for rotor blades, pipes, leaf springs, pump cases, high-performance boats, light airplanes, sporting goods, printed circuit boards, and housings for office machines.
