Trivalent Chrome Iridescent Yellow Passivation   TRIPASS YL 255 Introduction : TRIPASS YL 255 is a single component liquid Trivalent iridescent passivation for Alkaline and Acid Zinc plating process. It is completely free from Hexavalent Chrome. TRIPASS YL 255  provide a thick film passivate layer on both Alkaline and Chloride zinc deposits. TRIPASS YL 255  film achieve excelle corrosion resistance. TRIPASSYL 255  is easy to operate and suitable for both Rack and Barrel, Automatic and   manual plating process. TRIPASS YL 255  film can be further enhanced with the application of the post applied  Sealer  or Topcoats. Which   improve   functional properties   such   as   Corrosion   resistance   and     Coefficient   of   Friction. TRIPASS YL 255 Feature:- .Completely hexavalent chrome free. . Excellent receptivity on alkaline and chloride zinc...

  Trivalent Chrome Silverish Blue Passivation for Zinc Plating process Tripass SB 200  Introduction:  ■ Tripass SB 200 is a unique Tri-chrome passivation technology that produces “Blue-White finish  on Zinc Plating. This passivation can produce bright, haze-free “blue-white” colors including  blue, metallic and clear shades with a range of thickness from 50-100 nm.  ■ The color is determined by the thickness of the passivation and controlled by the chemical  concentration, pH, temperature, solution agitation and immersion time in working bath.  ■ These parameters determine the reaction rate and thus the color and thickness of the passivate. ■ Tripass SB 200 has demonstrated good color control and corrosion resistance (NSS) as a function  of bath aging. It is capable of meeting current automotive standards and ROHS directives.  Key Features: ■ TRIPASS SB 200 is Tri-chrome passivation chemistry, free of hexavalent chrome ■ Excellent c...
