LOCTITE® SI 593 is a black, general-purpose, 1-part RTV (room temperature vulcanizing) acetoxy silicone adhesive and sealant that moisture cures at room temperature to form a tough, flexible rubber seal.
It is designed for reliable sealing and bonding on a wide range of surfaces, and its non-slump formulation allows application on vertical or overhead surfaces. The cured sealant is highly resistant to extreme temperature cycling, UV light, and ozone.
