PN 901 300°C TG CYANATE ESTER PREPREG ¬ Achieves a Tg > 200°C (392ºF) after a cure temperature of 135-180°C (275-356ºF) Achieves a Tg > 300°C (573ºF) after a post-cure of 180-300°C (356-573ºF) Ideal for components exposed to high temperatures for short durations Good mechanical properties within large temperature range Low moisture absorption with high temperature wet performance Self-extinguishing and low smoke emission Easy handling and drape-ability (good tack life) Long shelf and shop life INTRODUCTION PN 901 is an ideal prepreg resin for high temperature composite applications, as it combines the ease of processing and handling convenience of epoxy resins, high temperature stability of polyimides, and flame and fire resistance of phenolics. A 120°C (248ºF) cure for 75 minutes combined with a post-cure, enables PN 901 to generate a Tg of up to 300⁰C (572ºF), making PN 901 ideal for applications in composite structures, which are exposed to very high temperatures for short durations. The flame and smoke characteristics of PN 901 composites show that this resin possesses superior flame retardant properties and holds a wide range of Aerospace grade FST (Fire/Smoke/Toxicity) standards.

PRODUCT INFORMATION PN 901 is available as prepreg resin matrix in unidirectional tapes and fabric prepregs with various types of fibres. Please consult your local sales contact for further information. Full contact details can be found at www.gurit.com. PREPREG PROPERTIES TRANSPORT & STORAGE When stored sealed & out of direct sunlight. STORAGE TEMP All prepreg materials should be stored in a freezer when not in use to maximise their useable life, since the low temperature reduces the reaction of resin and catalyst to virtually zero. However, even at -18°C (0ºF), the temperature of most...
