Epoxy system SR8500 / SD8601 (Slow)

Versatile epoxy system SR8500 / SD8601 for composite applications with slow hardener

Each kilo includes 0.74 kg resin + 0.26 kg hardener

The SR8500 / SD8601 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.

Slow hardener SD8601:
Reactivity adapted for manufacturing of large parts. Should be post cured at 40 ^oC before demoulding.

Applications:
Hand laminating
Injection
Filament winding
Cold or Hot press moulding
Casting
Adhesive
