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.  \nNSF International  \nRegistered to NSF Category P1 for use as a sealant where there is no possibility of food contact in and around food processing areas. Note: This is a regional approval. Please contact your local Technical Service Center for more information and clarification.  \nApproved by the Australian Gas Association Certificate number 4787 Class III rated working pressure 2000 kPa, working temperature-10 to 135°C. Note: This is a regional approval. Please contact your local Technical Service Center for more information and clarification.  \nEN 751-1  \nSealing materials for metallic threaded joints in contact with 1st, 2nd, and 3rd family gases and hot water; Part 1: Anaerobic jointing compounds. LOCTITE® 577™ has been tested and conforms to EN 751-1 for a class H compound and carries the DVGW certification.  \nHydrogen Certified Adhesive  \nLOCTITE® 577™ has been tested and conforms to GASTEC QA Approval requirement 214 (AR-214) .  \nNote: This is a regional approval.
