Enhances impact resistance and fracture toughness in thermoset composites without compromising thermal stability.
Compatible with epoxy, vinyl ester, and unsaturated polyester resin systems for seamless formulation integration.
Low-viscosity liquid form enables uniform dispersion and eliminates the need for high-shear mixing or solvent dilution.
Retains excellent mechanical properties after post-cure and long-term aging under humid and elevated-temperature conditions.
Halogen-free and REACH-compliant, supporting sustainable composite manufacturing requirements.
Aerospace structural components requiring high damage tolerance and fatigue resistance.
Wind turbine blade matrices for improved delamination resistance and service-life extension.
High-performance automotive under-hood and exterior composite parts exposed to thermal cycling.
Industrial tooling and molds where dimensional stability and crack resistance are critical.
Marine hulls and deck laminates demanding superior moisture resistance and impact resilience.
