CONATHANE EN-1554 is a polyether based polyurethane resin system primarily intended for use as a molding, encapsulating and potting compound for harness breakouts, watertight electrical connectors, cables, cable end seals, printed circuitry and other electrical components. The system also has utility in the casting or molding of mechanical parts and as a lining material for pumps, chutes and conveyors, where outstanding abrasion resistance is a necessity.

CONATHANE EN-1554 may be cured at room or elevated temperatures. CONATHANE EN-1554, when fully cured, is a tough, cold-flow resistant elastomer that has good resistance to oils, gasoline, JP-4 fuel, water, and seawater and also provides outstanding protection against corrosion or contamination. The system is funginert when tested in accordance with MIL-E-5262C and MIL-STD-810B.

Three primers have been developed for use in bonding EN-1554 to metals, neoprene, and polyvinyl chloride during the curing process. CONAP® AD-1146 is recommended for metals, CONAP® PR-1167 for neoprene, and CONAP® AD-1161 for polyvinyl chloride.
