It converts corrosion products and inhibits the corrosion process on various surfaces and products made of steel and cast iron with a rust layer thickness of up to 80 μm. Thanks to the presence of active zinc ions in its composition, it provides additional surface protection and extends the service life of steel products. Usage: Shake well before use. Clean the metal surface from loose (flaking) rust. Apply the product to the surface using a brush, roller, or spray method at a temperature not lower than +10°C on a dry degreased surface in two layers with an intermediate drying time of about 30 minutes. Painting the surface can be done after complete drying (at least 30 minutes at a temperature of +20°C). Temperature range of use: from +10 to +30°C. It does not lose its properties when frozen. Precipitation may occur during storage. Precautions: Caution! Contains acid. Use personal protective equipment (goggles, gloves) in a well-ventilated area. Do not swallow. Do not inhale the fumes. If it comes into contact with the skin, wash off with warm soapy water. Store in a tightly closed container. Keep in closed form. Keep out of reach of children and animals! Transportation and storage conditions: It is recommended to store in a dry, well-ventilated area, at a distance of at least 1 m from heat sources, at a temperature of +5°C to +25°C. Avoid direct sunlight. Store in a tightly closed container, separately from food products. Composition: Deionized water ≥30%, inorganic acid 15-30%, zinc salts ≤5%, functional additives ≤5%.
