ECA 106K is a low viscosity liquid anhydride epoxy curing agent based on methyltetrahydrophthalic anhydride. For convenience, it is pre-catalyzed with an accelerator that contributes to good glass transition temperature (Tg) in cured polymers. It is designed for use in converting epoxy resins to highly crosslinked polymers with excellent physical and electrical properties. ECA 106K is used in demanding applications including laminating and filament winding. It can also be used in electrical applications such as casting, potting and encapsulation.

ECA 106K will react with water to form diacids. This is normally undesirable, so ECA 106K should be stored in such a way that it is carefully protected from moisture contamination. For more details on the design of bulk storage for ECA 106K, consult the Dixie Chemical brochure "Epoxy Curing Agent Storage Requirements."

- Formulation Example
ECA 106K was formulated with a variety of epoxy resins. Viscosity was measured at 25°C, and gel time was measured at 100°C. Samples were cured for 1 hour at 120°C, followed by a post-cure of 1 hour at 220°C, and glass transition temperatures were measured using a differential scanning calorimeter. The following table summarizes these results:
