This report describes the evaluation of Hysol US0009 polyurethane as an encapsulant for the battery cable used on the MC1605B. The Hysol resin was selected for the application because it was reacted with a non-carcinogenic curing agent and because it exhibited superior mechanical, electrical, and hydrolytic properties over a wide temperature range.nThe Hysol encapsulant was evaluated to determine if it was superior to the EN-7 elastomer as a sealant against electrolyte migration to the interior of the cable.
