Formulated for structural components requiring FST properties, RP570 FR is a fire-retardant ultra-fast prepreg system which is cured and demouldable after 5 minutes at 160°C. This express resin system is principally designed for snap cure press moulding, however it can equally be used in conventional autoclave moulding and significantly reduces time in the autoclave – up to 50% less – thereby increasing productivity and lowering energy consumption per part.
RP570 FR is tested to Federal Aviation Requirements 25.853 Appendix F Part 1, AITM 2.0007 and 3.0005, UL94 V1 and FMVS Standard No.302.
Shortlisted for the Composites UK Industry Awards 2023 in the category of Innovation in Composite Materials.
