Excellent balance of mechanical strength and impact resistance for structural composite parts.
Low viscosity (250–350 cP at 25°C) enabling superior fiber wet-out and high filler loading capacity.
Good heat resistance with HDT above 85°C after post-cure, suitable for medium-temperature service environments.
Consistent reactivity profile ensuring reliable gel time control under standard MEKP initiation (1.0–1.5 wt%).
Low styrene emission formulation supporting improved workplace safety and regulatory compliance (VOC-reduced).
Fiberglass-reinforced plastic (FRP) tanks and chemical storage vessels.
Pultruded profiles including gratings, ladders, and structural beams.
Centrifugally cast pipes for water and wastewater infrastructure.
Sheet molding compound (SMC) components for electrical enclosures and transit interiors.
Marine deck cores and non-structural hull reinforcements.
