Description
Prevents the steel surfaces from tarnishing and corroding during the rinsing process after pickling with acids. KEBOCOR 238 A is an optimum formulation of several alkanolamine derivates of different molecular weight.
Benefits
- The product has buffering, sequestering and film forming properties.
- KEBOCOR 238 A is bound to the steel surface in an adsorptive manner and covers it with a thin non-conducting layer which mainly stops the cathodic partial reaction of the corrosion process.
- The buffering capacity of KEBOCOR 238 A prevents the formation of different pHzones on the surface so that stable local anodes cannot be formed which may cause corrosion products.
- In many cases a part of the rinsing water is fed to the pickling baths. For this reason KEBOCOR 238 A was formulated so that interferences with our pickling inhibitors such as ADACID 328 cannot take place.
- The active substances contained in KEBOCOR 238 A vaporize nearly residue-free at higher temperatures so that there are no carbonaceous surface contaminations to be feared during the subsequent annealing processes.
Dosing, Addition
The optimum concentration interval of the product varies between 500 and 1.000 g KEBOCOR 238 A per m3 rinsing water. Excessive dosing rates up to 1.500 g/m3 do not have any negative influence on the surface quality of the steel sheets.

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.
