CONATHANE EN-1554

Main features

Polyether-Based Polyurethane for Harness Breakouts
550% Cured Elongation
Water and Fuel Resistance

Product Description

CONATHANE® EN-1554 Polyurethane Encapsulant is a two-component polyether-based polyurethane system for molding, encapsulating, and potting harness breakouts, watertight connectors, cables, cable-end seals, printed circuitry, and other electrical components. The black or amber system uses a 100:33 mix ratio by weight and may be cured at room or elevated temperature. After cure, it forms a tough, cold-flow-resistant elastomer with documented resistance to oils, gasoline, JP-4 fuel, water, and seawater. Typical cured properties include Shore A 85 hardness, 550% elongation, and 600 V/mil dielectric strength.
