WEICON Rust-Shock 除锈松动喷雾，400 ml，UN 1950

Industrial-grade rust loosener spray designed to free seized and corroded threaded joints fast. Works like a “chemical wrench/screwdriver” by combining a chill (freeze) effect with strong capillary action so it can creep into micro-gaps and help break rust bonds in seconds. Suitable across maintenance and repair use cases where bolts, nuts, fittings, and other screw connections need to be opened without drama. Mineral oil-, grease- and silicone-free. Transport classification: UN 1950 (Aerosols).
