New TOP-BLACK treatment system in mass for black zinc-nickel

In an increasingly demanding market, Silga continues with the development of alternative finishes; it has in fact developed a new post treatment for the zinc-nickel process with black passivation.

The system allows to achieve aesthetic and technical high grade and is applicable on all types of articles, from small parts to geometrically complex items, ensuring reliability, efficiency and repeatability. With a deep black colouring, it guarantees aesthetic quality even for materials subjected to a dehydrogenation phase, inhibition of attack by aggressive agents, excellent resistance to corrosion according to international standards, high adhesion and high mechanical resistance (wear). It can be used on automotive parts, small mechanical parts, window and door frames and others.
