LS-81K is a formulated anhydride curing agent designed to be used in conjunction with epoxy bisphenol A or F resins for pultrusion applications requiring excellent physical properties. While these 100% epoxy resin systems have excellent pot life characteristics with low initial viscosities, cure rates at elevated temperatures are rapid.

  • Improved reactivity profile
  • Improved impact strength
  • Improved fracture toughness
  • Retention of glass transition temperature
  • Excellent adhesion to reinforcements such as glass and carbon fiber
