- 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 of dirt, dust, oil and any other contaminants.
Moisture curing begins immediately after the product is exposed to the atmosphere, therefore parts to be assembled should be mated within a few minutes after the product is dispensed.
Excess (uncured) material can be easily wiped away with non-polar solvents. Remove cured material using a knife or single edge razor blade.
The bond should be allowed to cure (e.g. seven days), before subjecting to heavy service loads
For full automatic applications a volumetric dispensing system is recommended
