Exceptionally high physical properties including low water absorbtion rates, high strength and toughness values & heat distortion temperature.

Orca 555/556 is a V/E, thixotropic resin designed for fabrication of small to large FRP parts at an ambient temperature. Orca 555/556 is pre-promoted for curing at room temperature with the addition of methyl ethyl ketone peroxide (MEKP) initiator. Orca 555/556 is designed to be used with both the spray-up and hand laid application technique.
