ST70FR is part of the range of SPRINT® products. This unique product 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 SP products from Gurit.

ST70FR 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 25-minute cure at 120°C. All of this can be achieved together with an outlife of 28 days at 21°C.

ST70FR is designed for vacuum bag processing and offers excellent mechanical performance on glass fibre reinforcements. Currently ST70FR 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. Other styles will be available to order.
