EPIKURE™ Curing Agent 3175



Product Description

EPIIKURE™ Curing Agent 3175 is a modified polyamide supplied at 100 percent solids. It is designed for use with epoxy resins to formulate high solids, two-component, ambient cure coatings. Coatings based on this resin offer long-term corrosion resistance and excellent chemical resistance.



  • Rapid cure response
  • Good working pot life
  • Long-term corrosion resistance
  • Excellent chemical and solvent resistance

General Information

EPIKURE Curing Agent 3175, when combined with a liquid epoxy resin like EPON™ Resin 828, produces coatings which exhibit a high level of performance while providing formulated VOC’s of less than 3.0 pounds/gallon. The VOC may be lowered through the use of reactive, low viscosity, epoxy functional modifiers such as HELOXY™ Modifier 68 or HELOXY Modifier 107. The use of these modifiers, while improving VOC, may have some effect on performance and should be evaluated on an individual basis.


This product does not contain non-reactive diluents or extenders, which provides the formulator with greater latitude in choosing solvents or diluents for a particular application. The pot life of primer formulations using EPIKURE Curing Agent 3175 with EPON Resin 828 varies from 4 to 10 hours depending on formulated viscosity. Formulations for brush and roll application (80-90 KU) will have a usable pot life of approximately four hours, while those prepared at spray viscosity (65-75 KU) will be usable for approximately 10 hours.


A combining ratio of 65% liquid epoxy (WPE=190) and 35% EPIKURE Curing Agent 3175 based on solids, represents a stoichiometric or 1/1 equivalence and provides the best overall performance for most applications.
