Quality products for burnishing a wide range of metals

Dipping workpieces in Emil Otto black oxidizing agent provides them with a protective coating. The resulting black mixed oxide layers effectively protect metallic surfaces from corrosion and at the same time provide an aesthetically pleasing appearance. The burnishing process is not only suitable for surface protection, but also as a preparation for further coatings, as burnished surfaces provide an optimum adhesion base for materials such as paints.

Emil Otto's burnishing solutions have been specially developed to burnish a variety of metals such as stainless steel and structural steels, tool steels, non-ferrous metals such as brass, bronze and copper as well as zinc, aluminum and their alloys.

Advantages of burnishing with our Emil Otto products:

Protection against corrosion thanks to abrasion and bending resistant layers

The layers created by burnishing protect the metal surface from damaging environmental influences, among other things. Black oxidized workpieces can be further processed without any problems and without damaging the protective layer. Emil Otto's burnishing solutions do not require any complicated preparation and can be used immediately.

From black dyeing to use as black dyeing mordant or etching ink, our products can be used in a variety of ways.
