GMS Composites EP – 280 Features & Benefits
- Variable cure cycle 80°C – 150°C
- Good surface finish
- Suitable for a range of structures and processes
- Excellent shelf life
- Wide range of fibre substrates available
- Made in Australia
Applications & Uses
EP-280 can be used to produce structural components with carbon, glass or aramid fibers. It can also be used in the construction of sandwich structures. The versatility of EP-280 means that large complex structures as well as small basic components can be produced. It is possible to utilise EP-280 in a number of industries and applications such as marine, sports and leisure, industrial components, automotive and wind turbine blades.
