Quality burnishing products for a wide range of metals

By using Emil Otto’s burnishing agents, workpieces are coated with a protective layer by immersion. The black mixed oxide layers that are created effectively protect the metallic surfaces from corrosion and at the same time provide an aesthetically appealing appearance. This process is suitable not only for surface protection but also as preparation for further coatings, since black oxidised surfaces act as an optimal primer for materials such as varnishes.

Emil Otto’s burnishing solutions have been specifically developed to process a wide variety of metals, such as stainless steel and construction steels, tool steels, non-ferrous metals such as brass, bronze and copper, as well as zinc, aluminium and their alloys.

Advantages of burnishing with our Emil Otto products

Corrosion protection with abrasion-resistant and rigid layers:

The layers produced by burnishing protect the metal surface, for example, from damaging environmental influences. Burnished workpieces can be further processed without difficulty and without damaging the protective layer. The burnishing solutions from Emil Otto do not require complicated preparation and are directly applicable.

From black colouring to use as a black colouring pickle or etching ink, our products can be used in numerous ways.

Application areas of our Emil Otto burnishing solutions:

Emil Otto’s burnishing solutions are used in a variety of industries and applications, including mechanical engineering and tool manufacturing, the finishing of copper, tin and zinc, the cold burnishing of sensitive workpieces and the treatment of heavy metals and special alloys.

A special feature of our Emil Otto burnishing solutions is their easy handling. Whether in industry or in trade, our solutions enable effective and simple surface treatment.

With its Nigrit burnishing solutions, Emil Otto stands for optimally protected, long-lasting and attractively finished metal surfaces.
