Reactive liquid modifier based on functionalized polyetheramine chemistry.
Enables significant improvement in impact resistance and fracture toughness of cured epoxy systems.
Offers excellent compatibility with standard DGEBA-type epoxy resins without phase separation.
Provides low viscosity for easy incorporation and homogeneous dispersion into epoxy formulations.
Supports room-temperature and elevated-temperature curing while maintaining thermal stability.
Aerospace composite matrices requiring high damage tolerance and fatigue resistance.
High-performance structural adhesives for automotive and rail bonding applications.
Toughened encapsulants and potting compounds for electronics protection.
Wind turbine blade resins demanding improved interlaminar shear strength and delamination resistance.
Industrial tooling and mold-making epoxy systems requiring dimensional stability and crack resistance.
