Conathane EN-1556 is a polyether based, non-MBOCA 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. ConathaneEN-1556, when fully cured, is a tough, cold-flow resistant elastomer that has good resistance to oils, gasoline, JP-4 fuel, water and sea water and also provides outstanding protection against corrosion or contamination. - The system also has use 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. ConathaneEN-1556 may be cured at room or elevated temperatures.
