EPIKURE™ Curing Agent 3233 is an unmodified, T403-type polyoxypropylenetriamine that has moderate reactivity, low viscosity, low color, low vapor pressure and high primary amine content. It resists “blush”, “bloom” and “sweat-out” in epoxy compositions. EPIKURE Curing Agent 3233 is a trifunctional primary amine curing agent with the idealized chemical structure shown below. Benefits include:

  • low viscosity and low vapor pressure
  • light color and improved color retention compared to conventional amine-cured epoxy systems
  • long pot life
  • improved flexibility and good impact resistance

EPIKURE™ Curing Agents 3200, 3223, 3234, and 3245 are unmodified aliphatic amines. They are used in a variety of applications including epoxy curing agents. Due to their tendency to form complexes with atmospheric carbon dioxide, particularly in humid conditions, they are most often formulated, adducted or otherwise reacted to inhibit amine blush. As members of the ethylene amine family, they lend themselves to a wide variety of chemical reactions and end use applications.

Due to their tendency to form complexes with atmospheric carbon dioxide, particularly in humid conditions, they are most often formulated, adducted or otherwise reacted to inhibit amine blush. Application Include:

  • Epoxy curing agents
  • Polyamides for inks and adhesives
  • Wet strength resins
  • Corrosion inhibitors
  • Oil and fuel additives
  • Chelating agents

EPIKURE™ Curing Agent 3253, a tertiary amine, is tris (dimethyl amino-methyl) phenol. It is most often used as a co-activating accelerator for other epoxy resin curing agents including polyamides, fatty amidoamines, polysulfides and acid anhydrides. Secondary uses include catalysts for urethane elastomers, isocyanurate foams, epoxy homopolymerization and isocyanate trimerization. Benefits include:

  • High reactivity
  • Low viscosity
  • Low vapor pressure
  • Good color

EPIKURE™ Curing Agent 3270, a modified aliphatic amine, is designed to rapidly cure thin sections of epoxy resin formulations at temperatures of 60 °F (15 °C) and above. EPIKURE 3270 is of special interest for decorative flooring and high-build coating applications because 100 percent reactive formulations of this type cure rapidly to clear, tough, mar-resistant films over a wide ambient temperature and relative humidity range. High-build floor coatings have been applied in one day and opened to traffic after an overnight cure period. Additionally, EPIKURE Curing Agent 3270 is well suited for fast setting equal volume adhesives. Benefits include:

  • Light color
  • Good mar resistance
  • Resistance to amine carbonate formation (“blush”, “bloom” or “sweat-out”)
  • Convenient combining ratio

EPIKURE™ Curing Agent 3271 is a modified aliphatic amine, low to moderate viscosity, fastsetting, high temperature resistant epoxy curing agent.  Benefits include:

  • Low viscosity; Fast-setting
  • High heat distortion temperatures
  • Modest blush resistance
  • Excellent chemical resistance

EPIKURE™ Curing Agent 3274, a moderately reactive, low viscosity aliphatic amine, is water insensitive and resists “blushing” “bloom’’ and “sweat-out” in epoxy compositions cured in high humidity environments. Other features are light color, improved color retention as compared to conventional amine cured epoxy systems, and long pot life. Benefits include:

  • Low color
  • Blush free
  • Sweat free

EPIKURE™ Curing Agent 3282, a very reactive modified aliphatic amine adduct, has been developed for applications where relatively short cure periods at room temperature are required. EPIKURE Curing Agent 3282 is normally used at a weight ratio of 20 parts per 100 parts of liquid epoxym resin. Thin sections, where exothermic heat is readily dissipated, require 4 to 8 hours for the composition to cure to handling strength. The composition reaches full cure after 4 to 7 days.

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. Benefits include:

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

EPIKURE™ Curing Agent 3295, a very low viscosity aliphatic amine adduct, is recommended for curing epoxy resins at room or moderately elevated temperatures. Its reduced vapor pressure, less critical combining ratio, superior electrical properties, and non-fuming characteristics make it safer and more convenient to handle than the aliphatic polyamines such as diethylenetriamine. EPIKURE 3295 is ideally suited for many casting, laminating, and impregnation operations and certain coating applications. It can be diluted with water and is useful as a curing agent for aqueous resin systems. Applications include:

  • Brush head potting compounds
  • Laminated and cast tooling
  • High-build maintenance coatings
  • Water-dilutable adhesives
