Notus Composites launches low-temperature curing epoxy prepreg

Notus Composites (Ras Al Khaimah, United Arab Emirates), a producer of epoxy prepreg materials, has launched its new NE7 low-temperature curing prepreg system. The new Notus NE7 formulation reportedly enables composite manufacturers to cure components at temperatures as low as 70˚C, reducing energy consumption and enabling more cost-effective tooling options.

Notus Composites has developed the new NE7 prepreg systems for applications across the marine, architecture, industrial and wind energy sectors. Existing prepreg manufacturers can now use more cost-effective composite tooling, with new prepreg users able to switch easily from existing infusion or wet laminating processes without creating new, expensive high-temperature tooling.

According to Notus Composites, NE7 prepregs can be cured at temperatures as low as 70˚C, with the standard cure cycle being 12 hours at 70˚C, matching the typical cycle time for an infused part with a component T_g of 85˚C. NE7 materials reportedly have a good outlife of 30 days at 20˚C and are available in all prepreg and Notus single-sided N1-Preg formats with unidirectional (UD), multiaxial and woven reinforcements. NE7 can also be supplied as a resin film.

Notus Composites’ EPFR-609 FR prepreg materials (tested and certified to NFPA 285, ASTM E84 and EN13501-1) are now available with the NE7 low-temperature curing technology, combining additional processing options with leading fire performance.
