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
