Orca Prepreg Resins & Adhesive

Orca Composites is pleased to offer a full range of prepreg possibilities with different resin systems and reinforcements including; carbon, glass, aramid and others. The resins can be tailored to specific liquid and cured properties to cover a full range of applications and industries. Cure temperatures range from 200˚F to 310˚F and shelf life storage requirements range from 12 mos. to 30 mos. providing temperatures do not exceed 75˚F and 0˚F, respectively.

Orca Composites offers a unique thermosetting epoxy matrix resin system featuring a one-year shelf life without refrigeration. This resin is currently used for tow/roving, unitape, fabric and braid and is available for carbon, glass, aramid and other fibers. Resin content, resin flow during cure, and tack levels can be tailored to suit your process requirements.
