Classics compounds
NUC 40
NUC 40 is a blue, fluid compound developed for nuclear power plant environments. It is applied in clamps, flanges, and line sealing, withstanding up to 240 bar and 700°C. Its low chlorine, fluorine, and sulfur content reduces corrosion risks in nuclear circuits.
NUC 40S
NUC 40S is a mid-granulometry version of NUC 40, designed for final compression in metallic enclosures and flanges. It combines nuclear safety compliance with effective sealing performance in demanding conditions.
NUC 42
NUC 42 is a very fluid, blue compound suitable for reinjections and for sealing small-gap flanges in nuclear applications. It ensures stable performance under high pressure and temperature, while maintaining compatibility with sensitive nuclear environments.
NUC 46
NUC 46 is an orange, flexible sealing paste designed to perform well in saturated steam or water conditions. It provides reliable resistance to thermal variations and is recommended for nuclear circuits operating between −160°C and 300°C, with pressures up to 120 bar.
NUC 46S
NUC 46S is a coarse-granulometry version of NUC 46, adapted for final compression. It is especially useful when adjustments are required in nuclear environments exposed to thermal fluctuations and saturated steam.
