EPOXY PREPREG SYSTEM
- Rubber toughened system
- Good resistance to microcracking
- Good surface finishes possible
- SE 85 - High Flow
- SE 85GT - Controlled Flow
- SE 85GT - Self adhesive - high peel strengths
The SE 85 series are toughened hot-melt, epoxy prepregs that offer an extremely good balance of mechanical properties. They are ideal for structural components where improved impact performance and resistance to resin microcracking is desired. SE 85 can be cured at 80°C, yet retains an outlife of up to 56 days at 23°C. With its 3/4 hour cure at 120°C, it is also suitable for the quick manufacture of parts, and is also used in the development of trial components.
SE 85 has high flow characteristics (SE 85GT medium flow) , so that heavy reinforcements can be easily wet out, and good consolidation can be achieved in very thick (>25mm) laminates, under just vacuum bag pressures. Its flow behaviour also means that it can produce excellent surface finishes when used in pressure-moulded components.
SE 85BL & SE 85GTBL is a black pigmented variant, often used in carbon fabrics to provide an excellent deep black gloss finish on the outer surface of carbon components such as yacht spars and race car parts.
SE 85 system can equally be used in sandwich structures with honeycomb and foam cores. In this application, depending on resin content, it can be used in a self-adhesive mode, although it is more commonly used in conjunction with the toughened SA 80 Adhesive Film.
