Excellent balance of mechanical strength and impact resistance for structural composite parts.
Good compatibility with standard MEKP (methyl ethyl ketone peroxide) initiators and low-reactivity accelerators.
Low styrene emission during processing, supporting improved workplace safety and regulatory compliance.
Consistent batch-to-batch viscosity and reactivity, ensuring reliable gel time control in open-mold and RTM processes.
Superior adhesion to fiberglass reinforcements and mineral fillers without requiring special surface treatment.
Fiberglass-reinforced plastic (FRP) tanks and chemical storage vessels.
Marine components including boat hulls, decks, and bulkheads.
Automotive body panels and under-hood non-structural parts.
Industrial grating, ductwork, and corrosion-resistant architectural cladding.
Wind turbine nacelle covers and blade root sections requiring dimensional stability.
