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
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.
