"Manufacturing Date Reference" section TYPICAL CURING PERFORMANCE. LOCTITE 577 is designed for the locking and sealing of metal threaded pipes and fittings. Particularly suitable for use Cure Speed vs. Substrate on stainless steel without the need for surface activation. The The rate of cure will depend on the substrate used. The graph product cures when confined in the absence of air between below shows the breakaway strength developed with time on close fitting metal surfaces and prevents loosening and M10 steel nuts and bolts compared to different materials and leakage from shock and vibration. The thixotropic nature of tested according to ISO 10964. LOCTITE 577 reduces the migration of liquid product after application to the substrate.

It not only works on active metals ( Steel brass, copper) but also on passive substrates such as stainless 75. steel and plated surfaces. The product offers gap performance Brass to mm ( in), high temperature performance and ate ichrom contamination tolerance. It cures in the presence of minor 50 zinc d surface contaminations from various oils, such as cutting, lubrication, anti-corrosion and protection fluids and cleaners 25. containing surfactants and corrosion inhibitors.
