Applications & Uses+
EP-285 can be used to produce structural components with carbon, glass or aramid fibres. It can also be used in the construction of sandwich structures. The versatility of EP-285 means that large complex structures as well as small basic components can be produced. It is possible to utilise EP-285 in a number of industries and applications such as marine, sports and leisure, industrial components, automotive and wind turbine blades.
