Name: Kaneka FM40 Toughener
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Kaneka FM40 Toughener

High-performance liquid epoxy resin modifier for enhanced fracture toughness without sacrificing glass transition temperature (T_g).
Reactive functionality enables covalent bonding with epoxy matrices, ensuring permanent toughening and long-term stability.
Low viscosity improves processability and facilitates homogeneous dispersion in standard epoxy formulations.
Halogen-free composition supports compliance with RoHS, REACH, and other environmental regulatory requirements.
Enables significant improvement in impact resistance and delamination resistance in cured composites.

Typical Applications Of Kaneka FM40 Toughener

Aerospace structural adhesives and prepreg systems requiring high damage tolerance.
Electronic encapsulants and underfill materials demanding thermal cycling reliability.
Wind turbine blade resins where fatigue resistance and interlaminar shear strength are critical.
High-performance composite tooling matrices used in autoclave and out-of-autoclave manufacturing.
Automotive under-hood components subject to thermal shock and mechanical vibration.
