Fire Retardant Laminating System
¬ Up to 10 hours working time at 25oC / 77oF; ideal for laminating large composite structures ¬ Meets BS476 part 6 & 7 class 2 ¬ Meets UL94 V0 rating ¬ Low initial mixed viscosity for fibre/fabric wet-out ¬ Low exotherm & shrinkage
INTRODUCTION Ampreg 21FR has been optimised for the manufacture of large composite structures using hand layup, and vacuum bagging techniques. Ampreg 21FR has been designed to give excellent mechanical and thermal properties from both ambient temperature cures, and moderate temperature postcures (50°C). This system uses Ampreg 21 hardeners and is available with a range of hardener speeds, from Fast to Ultra Slow.
TYPICAL APPLICATIONS Laminating of large composite structures for infrastructure, marine and rail applications.
