RFA570 has been principally designed for use with RP570 and RP570 FR eXpress cure epoxy prepregs as an adhesive for core bonding applications.
According to PRF, the characteristics of this product enable it to be cured in a press in four minutes at 140°C, thereby speeding up the processing of honeycomb sandwich panels - with either nomex or aluminium honeycombs. The product will also cure in autoclave, with a typical curing cycle of four minutes once the tool temperature has stabilised at 140°C. It is compatible with PRF’s range of epoxy prepreg systems.
Formulated as an epoxy-based composite primer/surfacing film, the new RF Primer film is compatible with PRF’s epoxy prepreg systems and provides a sacrificial surface that enables the constructor to eliminate paint priming. The film is laid as a first layer and then backed up with a prepreg laminate. It will co-cure with PRF’s epoxy prepreg formulations and will reduce the time required for surface preparation, thereby reducing cost-per-part.
