Epoxy system SR8500 / SD8605 (Fast)

 

Versatile epoxy system SR8500 / SD8605 for composite applications with fast hardener

Each kilo includes 0.74 kg resin + 0.26 kg hardener

The SR8500 / SD8605 system allows manufacturing of multiple kinds of composite parts that can work up to 70 ^oC continuously. Solvent and reactive diluent free, without any aromatic or CMR amines and very simple handling: One resin and two hardeners mixable in any proportions to achieve the desired reactivity. Curing at ambient temperature and post curing at 40 to 60 ^oC.

 

    Germanischer Llyod's certified
