EPIKURE™ Curing Agent 3164

 

Product Description

EPIKURE™ Curing Agent 3164 is a proprietary oligomeric polyamine curing agent for structural applications. Epoxy resins cured with EPIKURE Curing Agent 3164 can produce films, castings, or adhesive joints with a high degree of toughness and flexibility.

 

Benefits

  • Imparts highly flexible properties
  • Improved toughness compared to conventional polyamines
  • Improved combinations of elongation, strength, modulus, abrasion resistance, and tear resistance in comparison with those given by other "flexibilizing" curing agents
  • Strong low temperature properties of cured formulations
  • Good adhesion to a variety of substrates
  • Resistant to surface blush and amine exudates
  • Useful as formulating tool in blending with other curing agents to impart desired properties

General Information

EPIKURE Curing Agent 3164 is a proprietary oligomeric polyamine curing agent designed for use with epoxy resins to produce films, castings or adhesive joints with a high degree of toughness and flexibility. It is supplied as a solvent-free liquid.

 

The superior toughness and flexibility provided by EPIKURE Curing Agent 3164 in comparison with standard "polyamide" curing agents such as EPIKURE Curing Agent 3125, as well as a selection of other curing agents for "flexible" or "toughened" epoxy systems, is apparent from a comparison of Tables 1 and 2. This toughness and flexibility is achievable over a wide stoichiometric range. Some chemical resistance data for systems cured with EPIKURE Curing Agent 3164 are also shown in Table 2.
