Excellent balance of mechanical strength and impact resistance for structural composite parts.
Good reactivity with standard MEKP initiators, enabling reliable room-temperature and elevated-temperature curing.
Low viscosity (250–350 mPa·s at 25°C) for enhanced fiber wet-out and improved processability in RTM, pultrusion, and hand lay-up.
Superior weathering resistance and UV stability due to optimized molecular structure and inhibitor package.
Consistent batch-to-batch quality with strict raw material control and ISO-certified manufacturing.
Fiberglass-reinforced panels (FRP) for architectural cladding and façade systems.
Marine components including boat hulls, decks, and interior fittings.
Transportation parts such as truck body panels, bus shelters, and railway interior trim.
Industrial tanks and corrosion-resistant ducting for chemical handling environments.
Wind energy: non-structural nacelle covers and blade fairings.
