LOCTITE® SI 595 is a clear, general purpose, 1-part RTV (room temperature vulcanising) acetoxy silicone adhesive sealant, which cures at room temperature on exposure to moisture in the air to form a tough rubber seal. Its thixotropic nature allows for easy flow dispensing, while preventing the migration of liquid product once applied to the part. It won't slump in overhead or vertical applications, and has been formulated to withstand extreme temperature cycling, UV light and ozone. Please note this product cannot be painted.
