Widest range of formulations. Covers low-temp cure through 180°C (350°F) systems. Toughened grades for primary structures with excellent damage tolerance.

Bismaleimide (BMI)

High service temperature performance beyond standard epoxy capability. For aero-engine nacelles, pylons, and high-heat structural areas.

Phenolic

Fire, smoke, and toxicity (FST) performance for aircraft interiors. Meets FAR 25.853 requirements. Available with woven glass and carbon reinforcements.

Cyanate Ester

Ultra-high temperature and low dielectric properties for space structures, radomes, and satellite applications where dimensional stability is critical.

Cold Storage Required

All HexPly® prepregs must be stored at −18°C (0°F) in a sealed moisture-proof bag. Out-life at room temperature and shelf life vary by product — see individual data sheets. Coast-Line ships prepreg with proper cold chain packaging. Contact us to confirm current stock and expiry dates before ordering.
