LOCTITE® SI 5920

Known as LOCTITE 5920

Features and Benefits

Low strength, 1-part silicone sealant ideal for high temperature gasketing applications. Great on flexible flanges with machined or cast surfaces.
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 662°F (350°C). It is also used for electrical insulating applications.
