Araldite MY 721 Epoxy Resin 145 lb Drum
Araldite MY 721 is a tetrafunctional epoxy resin. When mixed with Aradur 5200 Hardener (sold separately), it is designed for fabricating high temperature performance composites by the filament winding process. The Araldite MY 721/Aradur 5200 system exhibits long pot life at process temperatures, yielding systems with high glass transition temperatures and excellent retention of mechanical performance, even at elevated temperatures.
