LOCTITE® SI 5699 Gasket Sealant
Known as LOCTITE 5699
Features and Benefits
Highly flexible, moisture-cure silicone sealant with excellent oil and water-glycol resistance. For rigid flange sealing, for example on transmissions and cast metal housings.
LOCTITE® SI 5699 is a flexible, form-in-place, room temperature vulcanizing (RTV) silicone sealant, which cures at room temperature on exposure to moisture in the air to form a tough rubber gasket. It is tack-free after just 10 minutes, and can be used on flexible, machined or cast surfaces, metal or plastic. Great for flange sealing and rigid flange sealing on, for example, transmissions and cast metal housings. Perfect for when water-glycol resistance is required.
- Highly flexible sealing for all types of flanges
- Tack-free after 30min
- Registered to NSF Category P1
- Oil and water-glycol resistant
- For corrosion-sensitive electrical assemblies
