Passivation product

Surfatek line of pickling, deoxidizing and descaling agents consists of professional products, made by mixtures of organic and inorganic acids. They are used in production contexts and for the maintenance of plants, equipments and machinaries, to remove superficial layers and inorganic reminders, such as thermal oxides (generated by welding or heat treatments), atmospheric oxides (rust) and encrustations (of any nature) Surfatek pickling agents can be liquid or thickened: Liquid pickling agents are used by plunging pieces to be treated inside tanks made of suitable material, or they can be used manually by means of brushes, brushes and sprayers. Thickened (gel) picklers are used to remove the thermal oxides generated by welding from vertical surfaces of large stainless steel products. All the pickling agents, after treatment, must be rinsed thoroughly with water; we recommend, for iron, steel and cast iron treatments, to neutralize the residual acidity on the surface with an alkaline passivating agent, such as PROTEK DIP CA or SPRAY TEK 893 P. This will prevent the rust from reforming within the short period. Surfatek deoxidizers are generally used to remove rust and calamine from ferrous and steel material and to remove light layers of oxide from yellow alloys, such as copper and brass. They are used by immersion in tanks made of suitable material, or, if it is necessary to shorten the processing times, in ultrasonic tanks or washing machines, thus availing themselves of the mechanical action that acts synergistically with the chemical action of the product.
