- Description
- Technical specification
If you are looking for a high-temperature resistant, moisture-curing sealant for corrosion-sensitive applications, LOCTITE® SI 5920 could be a great fit. Its thixotropic nature allows for easy flow dispensing, while preventing the migration of liquid product once applied to the part. It is ideal for sealing flexible flanges with machined or cast surfaces and is particularly suitable for high temperature applications up to 350°C (662°F). It is also used for electrical insulating applications.

How to use
For best performance bond surfaces should be clean and free of dirt, dust, oil and any other contaminants. Use LOCTITE® SF 7070, solvent based general parts cleaners, for the surface pre-treatment.
Moisture curing begins immediately after the product is exposed to the atmosphere, therefore parts to be assembled should be mated within a few minutes after the product is dispensed.
Excess (uncured) material can be easily wiped away with non-polar solvents. Remove cured material using a knife or single edge razor blade or simply use LOCTITE® SF 790. LOCTITE® SF 790 is a gasket remover designed to remove baked-on chemical gaskets, gasket cements and conventional gasket material from metal surfaces. It aerosol spray can make it easy to use, also for intricate shapes.
The bond should be allowed to cure (e.g. seven days), before subjecting to heavy service loads.
