Corrosion inhibitors

Benzotriazol, Tolyltriazol, Tolyltriazol Solution, Benzimidazol

- have excellent thermal and oxidative stability, as well as UV-light resistance.

- form a very strong bound protection film on Copper, its alloys and other metals and thus guarantee a long-term protection against corrosion and tarnishing (chemisorptive activity).

- do not influence the original appearance of the metal and leave no greasy film. The protection coat is wipe resistant and withstands cleaning with water and many organic solvents.

- are the classical passivators in the metal industry.

- do not reduce the heat transfer between metals and cooling water.

- protect the metal in open and closed cooling water circuits by building a barrier.

- are ecologically safe and low toxic : the activity of decomposition of biological sewage plants is not influenced by the usual, very small application concentrations (up to ca. 100 mg/l. ).

- no disadvantageous effect to the electric property of treated metal surfaces. Rather processes like soldering, coating, welding and electrolytic treatment will be facilitated and improved.

- have passivating effects and reduce the catalytic corrosion influence of copper/metal ions.

- can be well combined with other corrosion inhibitors like Borax, Molybdates, Nitrates, Nitrites, Phosphates, Silicates, Sodium Benzoate and organic phosphorus combinations and increase their effectiveness.

- offer corrosion protection also by steam phase inhibition.

- are already effective from 0,001 % and thus are very economically.
