Product Description
LOCTITE® SI 5910 is a one-component, paste-like silicone sealant for flexible metal or plastic flanges with machined or cast surfaces. The product cures at room temperature through atmospheric moisture (RTV), is resistant to motor oils, and is ideal for applications involving relative movement, such as oil pans, gearbox covers, or housings.
Thanks to its thixotropic properties, the material does not run – perfect for automated dosing or manual processing.
Product Advantages
- Oil and temperature resistant up to +200 °C
- Reliably fills gaps up to 1 mm
- Remains flexible, even with vibrations and relative movement
- Thixotropic, no flow on the flange surface
- Ideal for flexible flanges made of metal or plastic
Areas of Application
Engine and transmission construction, flange sealing for stamped sheet metal parts, mechanical engineering, pump housings, oil pans, control housing covers, plastic and metal flanges


Silicones, silicone oils, sprays
Casting and potting resins
