EPIKURE™ Curing Agent 3155

 

 

Product Description

EPIKURE Curing Agent 3155 is a low viscosity, modified polyamide epoxy curing agent based on dimerized fatty acid and polyamines. The low viscosity of EPIKURE Curing Agent 3155 allows formulation of products with high levels of pigmentation and use of little or no solvent, depending on end use application. It is well-suited for use in higher solids coating formulations where low volatile organic content (VOC) compliance is required.

 

Application Areas/Suggested Uses

  • High solids, VOC compliant industrial maintenance coating
  • Maintenance mastic coatings
  • Metal and plastic adhesives
  • High build marine primers and topcoats

 

Benefits

  • Good corrosion resistance
  • Good flexibility
  • Superior epoxy resin compatibility
  • Long pot life
  • Good blush resistance
  • Good chemical resistance
