- Technical specification
LOCTITE® 518 is a general purpose, primerless semi-flexible, form-in-place anaerobic flange sealant that cures when confined in the absence of air between close fitting metal surfaces. Tolerant of minor surface contaminants, it seals close fitting joints between rigid metal flanges and will flex with minor flange movements. Provides resistance to low pressures immediately after assembly of flanges. The product is particularly suitable for use on aluminum substrates where very good flexibility is needed. Typically used as a form-in-place gasket for pumps, thermostats, compressors, transmission housings and axle covers.
