EPIKURE™ Curing Agent 580


EPIKURE™ Curing Agent 580 is a light color, lower viscosity, modified cycloaliphatic amine curing agent that does not contain intentionally-added benzyl alcohol or nonylphenol. Any potential free BPA content is less than 10 ppm.  It can be used to develop flooring formulations with lower indoor air emissions.


  • Lower emissions (passes AGBB testing protocol)  
  • Excellent mechanical properties  
  • Improved hardness development and early water spot resistance @ 10 °C
  • 2 to 1 mix by volume (with liquid epoxy resin - WPE 190)
