Reactive liquid acrylic elastomer designed for high-efficiency toughening of standard and advanced epoxy resins.
Enables significant improvement in impact resistance and fracture toughness without compromising glass transition temperature (Tg) or modulus.
Excellent compatibility with common diglycidyl ether of bisphenol-A (DGEBA) and cycloaliphatic epoxy systems.
Low viscosity ensures easy handling, homogeneous dispersion, and simplified processing during compounding or formulation.
Stable shelf life under recommended storage conditions (unopened, <25°C, dry environment).
Aerospace composite matrices requiring damage tolerance and delamination resistance.
High-performance structural adhesives for automotive and rail transportation bonding.
Electronics encapsulants and underfills demanding thermal cycling reliability and crack suppression.
Wind turbine blade resin systems where fatigue resistance and interlaminar shear strength are critical.
Precision tooling and casting resins requiring dimensional stability alongside impact resilience.
