Gardacid P 4462/1 is a liquid sulfuric acidic pickling product used to remove laser and plasma cutting scale and rust from ferrous substrates. Gardacid P 4462/1 can also be used to clean and etch aluminum substrates. A fluoride additive is sometimes used with aluminum. The carefully balanced surfactant content of Gardacid P 4462/1 allows for the removal of oils and shop soils as well. It is designed for use in spray or immersion processes. Gardacid P 4462/1 is especially beneficial for use where pickling pre- phosphating with phosphoric acid would be a problem. Gardacid P 4462/1 does not form heavy sludge in the tank, or scale on heater surfaces, common problems with phosphoric acid-based products. This product does not contain phosphate, nitrate, fluoride, chelates or alkylphenol ethoxylates.
