Product information

Ampreg™ 31 has been optimised for the manufacture of large composite structures using hand layup and vacuum bagging techniques whilst offering improved health and safety.

The viscosity of Ampreg™ 31 has been optimised for good fabric wet-out whilst maintaining good drainage resistance for application on vertical surfaces. Ampreg™ 31 has been designed to give excellent mechanical and thermal properties from both ambient temperature cures and moderate temperature postcures (50°C). This system is available with the full range of Ampreg™ 3X hardener speeds, from Fast to Extra Slow.

The unique formulation offers improved health & safety through the careful selection of low toxicity raw materials as well as Light Reflective Technology which in conjunction with a UV light-source can detect droplets as small as 1mm for easy identification of contamination to improve industrial hygiene.



Ampreg™ 31 is DNV-GL & Lloyds Register certified.
