ALUMETCH 2 is a special product developed to provide excellent adhesion of the zincate layer on aluminum and aluminum alloys. Especially aluminum alloys containing high amounts of Magnesium and Silica can be subjected to the zincate process without any problems and can be coated directly in the Nickel Plating Bath. It provides a perfect surface to which the zincate layer can adhere by creating a homogeneous and excellent abrasion on the aluminum surface without any damage to the polished surface.
