Chain Extenders

Our ETHACURE® diamine chain extenders/crosslinkers are used to cure polyurethanes, epoxies and polyureas.

Easy to use, mix, meter and dispense, our liquid curatives allow you to easily adjust reaction time and eliminate dust exposure while saving time and improving product characteristics. ETHACURE curatives are ideal for spray coatings, cast elastomers, both hot cast and cold cast, as well as reaction injection moldings, adhesives and filament-wound pipe.
