Blue High-Performance RTV Silicone Gasket Maker, 300 mL

Loctite 37516 is LOCTITE® SI 587—a metallic-blue, oxime-cure RTV silicone designed for form-in-place gasketing and sealing on rigid or stamped flanges. The one-part, thixotropic paste skins quickly, cures at room temperature to a tough yet flexible elastomer, and provides excellent resistance to automotive and industrial oils. It is sensor-safe, low-odor, and non-corrosive, delivering reliable, leak-free seals in maintenance and OEM applications up to 500 °F (260 °C).
