Loctite 577

LOCTITE 577 is designed for the locking and sealing of metal threaded pipes and fittings. Particularly suitable for use on stainless steel without the need for surface activation. The product cures when confined in the absence of air between close fitting metal surfaces and prevents loosening and leakage from shock and vibration. The thixotropic nature of LOCTITE 577 reduces the migration of liquid product after application to the substrate. LOCTITE 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 surfaces. The product offers gap performance to 0.25 mm (0.01 in) high temperature performance and contamination tolerance. It 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.
