Reactive liquid modifier enabling phase-separated morphology for enhanced fracture toughness without sacrificing Tg.
Excellent compatibility with standard DGEBA-type epoxy resins and common amine or anhydride curing agents.
Low viscosity (< 500 mPa·s at 25°C) facilitates easy incorporation and homogeneous dispersion in epoxy formulations.
Significantly improves impact resistance and delamination resistance in cured composites and adhesives.
Enables high-performance toughening at low addition levels (typically 5–15 wt% relative to epoxy resin).
Aerospace structural adhesives and composite matrix resins.
High-reliability electronic encapsulants and underfills.
Wind turbine blade bonding and prepreg matrices.
Automotive under-hood components and carbon fiber reinforced parts.
Industrial tooling and high-strength castings requiring crack arrest capability.
