Scope of application
Removing weld scales and temper colours, old disturbed passive layers, carbon steel deposits, oxides of contaminant materials, and marks caused by handling. Intended for low-alloy and austenitic materials.
Read safety instructions before use. Shake and stir Antox 71 E Plus until homogeneous. Apply using a plastic ANTOX brush, creating a consistent-thickness layer over the weld and its surrounding area. Depending on a weld type and ambient temperature, allow to act for 30–90 minutes. Rinse with min. 12 MPa pressure water. In the event of short welds, rinsing is also possible using running water while mechanically cleaning the area with a stainless steel or plastic brush or sponge. Keep rinsing until the pickled surface and rinse water are pH neutral. If the pickled surface is not completely clean, repeat the entire process.
Waste water disposal
Since rinse waste water is acidic and contains heavy metals, it must be collected. Before rinsing off pickling paste, neutralizing paste can be applied to the surface in order to neutralize the rinse water. The collected rinse water (even if neutralized) must be disposed of ecologically. Either use own waste water treatment plant (consult the plant operator) or engage a specialized company to dispose of it.
Antox 71 E Plus contains nitric acid and hydrofluoric acid. The product label contains instructions to be adhered to. Further information is in a safety data list and is available on demand. Persons must wear protective clothing, gloves, and a face shield.
1 kg of Antox 71 E Plus can treat 40–90 metres of welds
