Applications & Uses+
EP-290 can be used to produce structural components with carbon, glass or aramid fibres. The versatility of EP-290 means that large complex structures, as well as, small basic components can be produced. It is possible to utilise EP-290 in a number of industries and applications such as marine, sports and leisure, industrial components, automotive and wind turbine blades.

Technical Details & Test Data+
The versatility of GMS Composites EP-290 means a range of cure cycles, pressures and ramp up rates can be adopted all of which will depend greatly on the part being produced. Below is a guide to cure cycles.
- Heat ramp up rate – 2°C / min
- Pressure – 1 bar
Values are indicative of small samples of neat resin formulation. Gel times may vary significantly in composites depending on fibre content and laminate thickness.
