BOSS® 322 100% RTV silicone sealant is a paste-like, one-component material that cures to a tough, rubbery solid when exposed to moisture in the air. Since it will not flow under its own weight, this sealant can be applied overhead or on sidewall joints and surfaces without sagging, slumping, or running off. It will adhere to clean metal, glass, most types of wood, silicone resin, vulcanized silicone rubber, ceramic, natural and synthetic fibre, as well as painted and many plastic surfaces.



Available in a variety of colours including clear, white, black, aluminium, and bronze.


Available in standard 300 gms caulking cartridges.
