Epoxy system SR1126 / SD8203 (Medium)

Fire resistant epoxy laminating system SR1126/SD8203 with medium hardener

Each kilo includes 0.83 kg resin + 0.17 kg hardener

Auto extinguishing laminating epoxy system. It creates low smokes and low toxicity smokes. It exhibits good temperature resistance and is bromine free. With high temperature or fire, the system expands, producing solid char barrier that protects inner materials from heat and flames. This system allows to get UL94 V0 and FAR 25 laminate parts as well as AIRBUS and BOEING standards concerning fumes and fume toxicity (please see data sheet for all details concerning FAR 25 and UL94 V0 approvals).

Medium hardener SD8203:
Suitable for manufacturing medium to large part by hand lay, press moulding and vacuum bagging. Post cure at 40 °C minimum before unmoulding. Designed for high performance composites, with service temperature up to 60-70 °C.
