ANIM® ZN924 trivalent chromium black passiavtion sealing technology is a kind of new trivalent chromium water-soluble sealing agent excluding silicate and resin, which can improve the brightness and the corrosion resistance.
Characteristics of the products
1. It is taken as the post-dipping treatment of trivalent chromium, and does not contain polymer resin and silicate.
1. It is taken as the post-dipping treatment of trivalent chromium, and does not contain polymer resin and silicate. 2. It is specially designed to meet the industrial requirement that cannot use traditional sealing agent at outer most layers, so as to improve the performance of the passivation film.
3. Only dipping-drying working procedure can greatly improve the appearance and corrosion resistance of the black passication film.
4. Because it does not contain resin, there is no need of rack stripping procedure, and is applicable for continuous production.
