LS Formulated Anhydrides
The LS Series
Formulated Anhydrides

The LS Series products are low viscosity, anhydride based curing agents.  These products are pre-catalyzed to react readily with epoxy resins, and have been formulated to give improved flexibility and toughness to rapidly cured parts.  Other benefits include:

  • Improved reactivity profile
  • Improved impact strength
  • Improved fracture toughness
  • Retention of glass transition temperature

In addition, these products have been formulated with an additive that forms a second phase on gelation, leading to a toughened cure compared to cures of epoxy resins with standard anhydrides.  These features-coupled with excellent adhesion to reinforcements such as glass and carbon fiber-make these systems excellent choices for many composite processes, including pultrusion, filament winding and resin transfer molding.
