High reactivity with standard MEKP initiators for rapid room-temperature cure.
Excellent mechanical strength and dimensional stability after curing.
Good resistance to water, alkalis, and mild acids in cured form.
Low viscosity enables easy handling, wet-out of reinforcements, and air release.
Formulated for consistent performance in sheet molding compound (SMC) and bulk molding compound (BMC) processes.
Automotive exterior and structural components (e.g., body panels, under-hood parts).
Industrial enclosures and electrical housings requiring flame-retardant properties.
Building and construction products including roofing tiles and façade elements.
Transportation interiors and semi-structural parts for rail and bus applications.
Marine deck and hull components where moisture resistance and stiffness are critical.
