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.

The rate of cure will depend on the substrate, bond gap, activator and temperature (Consult the Technical Data Sheet).

Warning:

1. The product is not recommended for use as a sealant for chlorine or other strong oxidizing materials.
2. The percentage of initial strength may decrease or fail by changing temperature, chemical/solvent resistance, gap size and aging.
3. It is important to check for compatibility of the washing solution with the adhesive (TDS).
4. This product is not normally recommended for use on plastics (particularly thermoplastic materials where stress cracking of the plastic could result).

Conditions for safe storage:

8 °C to 21 °C. Storage below 8 °C or greater than 28 °C can adversely affect product properties. Material removed from containers may be contaminated during use. Do not return a product to the original container. Henkel Corporation cannot assume responsibility for the product which has been contaminated or stored under conditions other than those previously indicated. If additional information is required, please contact your local Technical Service Center or Customer Service Representative.

For Disassembly 1. Remove with standard hand tools. 2. Where hand tools do not work because of excessive engagement length or large diameters (over 1″), apply localized heat to approximately 250 °C (480F). Disassemble while hot.

For Cleanup 1. Cured product can be removed with a combination of soaking in a LOCTITE® solvent and mechanical abrasion such as a wire brush.
