Converts corrosion products and inhibits the corrosion process on various surfaces and products made of steel and cast iron with a layer thickness of rust up to 80 microns. Thanks to the presence of active zinc ions in the composition, it provides additional surface protection and extends the service life of steel products. Application method: shake well before use. Clean the metal surface from loose (flaking) rust. Apply the product to the surface with a brush, roller, or spray method at an ambient temperature not lower than +10°C on a dry degreased surface in two layers with intermediate drying of about 30 minutes. The surface can be painted after the complete drying (no less than 30 minutes at a temperature of +20°C). It does not lose its properties when frozen. Sediment may occur during storage. Temperature range of application: from +10 to +30 °C. Volume: 60 ml Composition: Desalinated water ≥30%, inorganic acid 15-30%, zinc salts ≤5%, functional additives ≤5%.
