Cytec 1556 is a non-MBOCA, polyurethane material that is specifically designed for potting, encapsulating and molding for electrical connectors, printed circuitry, harness breakouts, and cable end seals. This material is also capable of molding or casting mechanical parts and lining material for chutes, pumps and conveyors. The advanced polyurethane resin also meets or exceeds the requirements of MIL-M-24041-C.
When Cytec Conathane EN-1556 is fully cured, it becomes a cold-flow resistant, tough elastomer that provides excellent protection from contamination and corrosion. The innovative material has two parts and provides excellent resistance to a wide variety of chemicals including gasoline, oils, ocean water, and water. Cytec 1556 can be cured either by room or elevated temperatures. At a temperature of 25 degrees Celsius, Part A has a viscosity of 18,000 cps. At the same temperature, Part B will have a viscosity of 3,000 cps. A temperature of 77 degrees Fahrenheit, the demolding time of the material will be 24 hours and the complete cure with be approximately 10 to 14 days. Elevating the temperature to 212 degrees Fahrenheit will decrease the demolding time to 30 minutes and the complete cure will take 8 to 10 hours. The amount of mold mass, material and complexity of the substrates will cause the curing time to vary. Once it is fully cured, it will be a clear amber color or a black solid.
The understanding of the proper safety precautions, application methods and storage of the material is extremely important. Cytec 1556 will have a shelf life of 15 months from the date of manufacture when it is properly stored in its original tightly sealed container at a temperature below 90 degrees Fahrenheit. Part A will react with atmospheric moisture because it is an isocyanate prepolymer. When mixing and applying Cytec EN-1556, it is high recommended to do so in a well-ventilated area. This material contains some traces of free toluene diisocyanate (TDI). Avoid contact with the skin and breathing in the toxic vapors. If contact is made with the polyurethane, wash the area with soap and water.
