Designed for treating metal surfaces to remove and prevent corrosion or rust. Protects the treated surface from further atmospheric and climatic influences. Passivates the metal surface by converting corrosion products into a solid coating that can serve as a base for painting. Method of application: Shake well before use. Clean the metal surface from loose (peeling) rust. Apply the product to the surface with 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. The surface can be painted after the surface has completely dried (no less than 30 minutes at a temperature of +20°C). Temperature range of application: from +10°C to +30°C. Volume: 500 ml Composition: Desalinated water ≥30%, inorganic acid 15-30%, functional additives ≤5%.
