Features & Benefits+
Applications & Uses+
EP-530 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 product is self-extinguishing and meets the classification of UL 94 V-0. As such it can be utilised in industries such as rail, marine or other transport applications where FST performance is critical.
