LOCTITE 518 cures when confined in the absence of air between close-fitting metal surfaces. It is an anaerobic gasketing material designed for use on rigid iron, aluminum, and steel flanged mating surfaces. LOCTITE 518 fills gaps up to 0.25mm and forms a flexible, chemical-resistant seal that will not tear or decay. Parts disassemble easily, even after extended service. Typical applications include sealing close-fitting joints between rigid metal faces and flanges. It is also used as a formed-in-place gasket on rigid flanged connections, e.g. transmissions and motor housings. Prevents leakage: It fills all gaps between the mating flange parts and cures into a hard thermoset plastic that fills all surface irregularities providing 100% seal. Adapts to flange surface irregularities and scratches up to 0.25 mm. Eliminates gasket compression set. Reduces inventory cost and complexity as one tube can make many different shapes and sizes of gaskets. Provides instant seal. Ideal for use on rigid metal parts, e.g. cast iron components and pump housings. High oil resistance. Excellent water and glycol resistance.
