Known as Loctite Superflex White RTV Silicone
Features and Benefits
General purpose, 1-part silicone adhesive sealant, which cures at room temperature to form a tough rubber seal. Can also be used for potting and coating.
LOCTITE® SI 594 is a white, general purpose, 1-part RTV (room temperature vulcanizing) 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. Will not slump in overhead or vertical applications. It has been formulated to withstand extreme temperature cycling, UV light, and ozone. Please note this product cannot be painted.
