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