Features Of Kaneka Kane Ace MX-139 Epoxy Toughener

Reactive liquid acrylic elastomer designed for effective toughening of diglycidyl ether of bisphenol-A (DGEBA) and other standard epoxy resins.
Enables significant improvement in fracture toughness and impact resistance without compromising glass transition temperature (T_g) or modulus.
Offers excellent compatibility with common epoxy systems, enabling homogeneous phase morphology upon curing.
Low viscosity facilitates easy handling, metering, and uniform dispersion into epoxy formulations.
Provides enhanced peel strength and delamination resistance in structural adhesive and composite applications.
