efficient inhibitor for the protection of metal surfaces during the pickling in sulphuric acid baths. ADACID 332 can be used in pickling plants of any kind with or without regeneration plants up to a max. temperature of 100°C.


    • Is soluble without residues in sulphuric acid solutions.
    • The liquid form allows a simple dosing.
    • Is free from chloride and foam so that any interruptions in regenerations plants are avoided.
    • In addition to the inhibitors ADACID 332 contains dispersants and surfactants with which clear and proper surfaces are obtained.
    • Subsequent surface refinements are not affected.
    • The formulation of ADACID 332 avoids excessive picklings and reduces the acid consumption.

    Dosing, Addition

    ADACID 332 is added direct to the pickling bath. The consumption is dependent on the acid concentration, the temperature and the sensitiveness of the material to acids. The dosing rates depend on the quantity passed, quality and surface size of the material to be pickled.

    The dosing rates mentioned below are standard values:

      • Stationary or continuous pickling plants without regeneration: system 500-1.000 g ADACID 332/m3 of pickling solution ready for use for new preparation. When the protective capacity abates add approx. 250 g/m3.
      • Stationary or pass through pickling plants with regeneration system: New preparation of bath see a), then 35-100 g ADACID 332/t pickled material.
      • Continuous pickling plants with regeneration system: 100-250 g ADACID 332/m3 of pickling solution ready for use for new preparation, then 10-30 g ADACID 332/t pickled material.

        The products shown on our website are only a selection of our entire product range. There is no universal remedy for the rapid removal of impurities. Some can be removed well with alkaline agents, others better in the acidic range. The large variety of conceivable cleaning problems and the large number of additives, inhibitors and ready-to-use cleaning solutions offered by us make it advisable to obtain detailed advice before starting cleaning.
        The same applies to inhibitors, defoamers, scale preventers, corrosion inhibitors, pickling inhibitors, etc. Depending on the plant, material, product and the type of boiler/cooling water is used, different individual challenges arise. We are well equipped for them.

        Talk to us, we will be happy to help!
        On request, we can analyze deposits in our laboratory and develop a cleaning strategy based on our many years of experience, taking into account the conditions on site.
