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.
