EPIKURE™ Curing Agent 3389


EPIKURE™ Curing Agent 3389 is a very low viscosity modified amine designed for use with EPON™ Resin 896 to give formulations that offer a superior degree of chemical resistance.  The cured system demonstrates superior mechanical strength and high heat deflection temperature (HDT) even without post cure at elevated temperatures. 


It is important to note that only the combination of EPON Resin 896 with EPIKURE Curing Agent 3389 provides the highest chemical resistance.  Do not modify this system with additional diluents or by adding solvents or modifiers because this will decrease its performance.  EPON Resin 896 and EPIKURE Curing Agent 3389 are designed to work together to provide low viscosity and superior chemical resistance for the application areas listed below.


  • Superior chemical resistance when used with EPON Resin 896
  • Low viscosity
  • High reactivity even down to 5 °C
