LOCTITE 518 is a multi-purpose, medium-strength joint-forming product with excellent tolerance to contamination. Recommended for use on cast iron, steel and aluminum flanges.
LOCTITE® 518 cures in the absence of air, when confined between close-fitting metal surfaces. It is an anaerobic gasket-forming material designed for use between flanged mating surfaces of rigid iron, aluminum and steel. LOCTITE 518 fills gaps up to 0.25 mm and forms a flexible, chemical resistant seal that will not break or deteriorate. The parts are easily disassembled, even after a long time. Typical applications include sealing tight joints between rigid metal surfaces and flanges. Also used as a formed-in-place gasket in rigid flanged connections, e.g. e.g. in gearboxes and engine crankcases.
