EPIKURE™ Curing Agent 3290

 

 

Product Description

EPIKURE™ Curing Agent 3290 is a modified aliphatic amine, light colored, low viscosity epoxy curing agent. Systems cured with EPIKURE 3290 exhibit excellent solvent resistance. Mix ratios are less critical than standard polyamines.

 

Application Areas/Suggested Uses

  • Metal and plastic adhesives
  • Small castings
  • Laminates
  • Electrical potting
  • Automotive body patching compounds
  • Tooling compounds
 

 

Benefits

  • Reduced vapor pressure
  • Low shrinkage
  • Less critical mix ratios
  • Good chemical resistance
  • Low mixed viscosity
