EPIKURE™ Curing Agent 3383

 

 

Product Description

EPIKURE Curing Agent 3383 is a low viscosity, modified cycloaliphatic amine, light-colored,

epoxy curing agent designed for civil engineering, building and construction applications.

EPIKURE 3383 is excellent where high gloss, self-leveling, smooth, chemically resistant,

light fast properties are required. EPIKURE 3383 is compatible with most EPIKURE 3000

series curing agents.

 

Application Areas/Suggested Uses

  • Plastic and metal adhesives
  • Electric potting and casting
  • Civil engineering, building and construction:
  • High-build synthetic mortars
  • Self-leveling industrial flooring
  • Chemically resistant concrete coatings
  • Color fast tile grouts
  • Primers

 

Benefits

  • Excellent smooth, self-leveling films
  • Excellent chemical resistance
  • Excellent blush resistance
  • Light fast
  • Low viscosity
  • Light color
  • Compatible with most EPI-CURE 3000 series curing agents
