LOCTITE(R) 577* is designed for the locking and sealing of metal threaded pipes and fittingsParticularly suitable for use on stainless steel without the need for surface activationThe product cures when confined in the absence of air between close fitting metal surfaces and prevents loosening and leakage from shock and vibrationThe thixotropic nature of LOCTITE(R) 577* reduces the migration of liquid product after application to the substrateLOCTITE(R) 577* provides robust curing performance. It not only works on active metals (e.g. brass, copper) but also on passive substrates such as stainless steel and plated surfacesThe product offers gap performance to 0.25 mm (0.01 in), high temperature performance and contamination toleranceIt cures in the presence of minor surface contaminations from various oils, such as cutting, lubrication, anti-corrosion and protection fluids and cleaners containing surfactants and corrosion inhibitors
