Inhibitor F/302
Inhibitor F/302 - is a liquid pickling inhibitor for steel and cast iron. The product is a mixture of pickling inhibitors, non-ionogenic tensides and complexing substances. Product F/302 is especially designed as inhibiting additive to pickling baths on the basis of hydrogen chloride acid and sulphuric acid and their mixture. It inhibits the surface of ferrous metals and, to a smaller extent, also inhibits the surface of zinc and other metals. It significantly reduces hydrogenization of steel and makes the pickled surface of metals finer and more even. It is used in acids, after preceding degreasing in alkaline, acid or tenzide agents.
