LOCTITE® SI 5399
Known as LOCTITE 5399
Features and Benefits
A 1-part, multi-purpose, thixotropic silicone adhesive for industrial applications where a high heat tolerance is required.
LOCTITE® SI 5399 is a red, acetoxy silicone-based bonding and sealing agent for high-temperature industrial applications up to 350°C (662°F). It’s typically used for industrial ovens and heating engineering applications, but it is also suitable for household heat appliances such as ovens, heat exchangers, and water heaters. Its thixotropic nature makes it easy to apply and reduces liquid migration after application. LOCTITE SI 5399 cures at room temperature.
- Temperature resistant up to 350°C (662°F)
- Room Temperature Vulcanization (RTV) cure
- Enhances load-bearing & shock absorbing characteristics of bond area
