Reactive acrylic-based impact modifier designed for enhanced toughness in thermoset resins.
Enables excellent compatibility and dispersion in epoxy, unsaturated polyester, and vinyl ester systems.
Improves fracture resistance without significantly compromising heat deflection temperature (HDT) or modulus.
Low volatility and high thermal stability support processing at elevated temperatures.
Reduces microcracking and delamination in cured composites under mechanical and thermal stress.
Aerospace-grade structural adhesives and prepreg matrices.
High-performance wind turbine blade resins.
Automotive under-hood composite components requiring impact durability.
Electrical insulation materials for high-voltage equipment.
Marine gelcoats and laminating resins exposed to cyclic loading.
