WEICON Rust Shock 400 ml

WEICON Rust Shock – agent for loosening seized and corroded screw connections. An advanced penetrating agent (a "chemical spanner") for fast dismantling of the most stubborn, seized and heavily corroded threaded connections. It combines a thermal shock (rapid cooling) with extreme capillary action. The sudden cooling makes the rust shrink and crack, creating micro-gaps into which the active agent penetrates immediately and deeply, dissolving the corrosion and loosening the thread in just a few seconds. The product is an indispensable tool in precision mechanics, car workshops, heavy industry and everyday maintenance work. Key advantages: Thermal shock effect: rapidly freezes the sprayed surface, creating micro-cracks in the corrosion layer and making penetration easier. Extreme capillary action: the liquid quickly penetrates the narrowest thread gaps and reaches the source of seizure directly. Clean, residue-free formula: completely free of mineral oils, greases and silicone, so it leaves no sticky residues. Fast action: loosens the connection in about 10–20 seconds after application. Safe for materials: dissolves rust without damaging the metal parts. Applications: Loosening seized, rusted and stuck bolts, nuts, pins and studs Dismantling seized connections in exhaust systems, suspensions and other automotive components Overhaul and maintenance work on industrial, agricultural and construction machinery Servicing valves and fittings, pipelines and outdoor steel structures Technical information: Capacity: 400 ml Action time: after approx. 10–20 seconds Colour: colourless / transparent Odour: solvent Free of silicone and mineral oils: yes
