FIRE RETARDANT STRUCTURAL SPRINT™ ¬ Award winning SPRINT™ matrix ¬ Low smoke toxicity ¬ Suitable for rail, marine and civil engineering structures ¬ Self extinguishing ¬ Halogen-free ¬ 70°C Curable ¬ Suitable for Lloyds and MCA Compliant Structures ¬ Suitable for monolithic and sandwich structures ¬ Excellent laminate quality, from vacuum-only processing INTRODUCTION ST 70FR is part of the range of SPRINT™ products. This unique range provides technically and commercially competitive engineering materials, ideal for use either solely, or in conjunction with other products from within the product range along with other Gurit products.ST 70FR is a fire retardant hot melt, Diuron free epoxy SPRINT™. This is ideally suited to the manufacture of thick sections requiring fire protection. It can be cured at temperatures as low as 70°C, but can also be used for the rapid manufacture of components through its 60-minute cure at 110°C. All of this can be achieved together with an outlife of 14 days at 21°C.ST 70FR is designed for vacuum bag processing and offers excellent mechanical performance on glass fibre reinforcements. Currently ST 70FR is manufactured into a Single Sided SPRINT™ structure primarily with fibreglass reinforcements such as woven WRE581T, WRE850T fabrics and multiaxial XE905 and QE1174 stitched fabrics.
