Epoxy Resin
Epoxies generally out-perform most other resin types in terms of mechanical properties and resistance to environmental degradation, which leads to their almost exclusive use in aircraft components. As a laminating resin their increased adhesive properties and resistance to water degradation make these resins ideal for use in applications such as boat building. Epoxies differ from polyester resins in that they are cured by a 'hardener' rather than a catalyst. Since the hardener molecules 'co-react' with the epoxy molecules in a fixed ratio, it is essential that the correct mix ratio is obtained between resin and hardener to ensure that a complete reaction takes place. If they are not mixed in the correct ratios, unreacted resin or hardener will remain within the matrix which will negatively affect the final properties after cure.

Ampreg 22 Epoxy laminating system

Ampreg 22 is an epoxy laminating system that has been developed from the successful and widely used Ampreg 20. It is intended for both wet lay-up and vacuum bagging processes. Its long working time, low exotherm and low viscosity make it ideal for the manufacture of large, high performance composite structures. The system is Lloyds and Germanischer Lloyds approved.

Ampreg 21 Epoxy laminating system
Ampreg 21 has been optimised for the manufacture of large composite structures using hand layup, and vacuum bagging techniques. The relatively low initial mixed viscosity of Ampreg 21 allows easy wet out of heavyweight reinforcements. It has been formulated to provide excellent Health and Safety. Ampreg 21 has been designed to give excellent mechanical and thermal properties from both ambient temperature cures, and moderate temperature post cures (50°C). This system is available with a range of non pigmented hardeners, from Fast to Extra Slow.

Prime 20 LV
PRIME 20 is an epoxy infusion resin specifically designed for use in a variety of resin infusion processes. It has a very low mixed viscosity and long working time, allowing large parts with complex reinforcements to be infused successfully in one operation. PRIME 20 is available with a range of hardeners giving different working times and cure speeds.
