- Description
- Technical specification
- Question & answer
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.

How to use
For best performance bond surfaces should be clean and free from grease.
Moisture curing begins immediately after the product is exposed to the atmosphere; therefore, the parts to be assembled should be mated within a few minutes after the product is dispensed. The bond should be allowed to cure (e.g., seven days) before being subjected to heavy service loads.
Excess material can be easily wiped away with non-polar solvents, e.g. mineral spirits or naptha based cleaners.
This product is not recommended for contact with gasoline. For full automatic applications a volumetric dispensing system is recommended.
