trivalent chrome plating process

TriMac CP-200 is a trivalent chromium plating process developed for electroplating chromium deposits that are resistant to calcium chloride-based snow melting salts. It delivers a color and plating speed close to those obtained from hexavalent chromium electroplating baths. Read more

trimac iii

The world's leading trivalent chromium plating process.

TriMacIII is the “industry standard” for trivalent chromium plating. TriMacIII contains zero carcinogenic hexavalent chromium, It is able to achieve a deposit thickness in excess of 0.3 microns (12 microinches), whilst providing a deposit that is virtually indistinguishable from hexavalent chromium deposits. The system is easy and economical to operate. TriMacIII is automotive-approved for both interior and exterior applications.

TriMac III meets automotive chromium specifications for interior and exterior applications. When measured to the Q-Color standard, it compares as follows to traditional bright chromium plate:trivalent chrome plating

trimac cp-200

A trivalent chromium plating process producing deposits resistant to calcium chloride snow melting salts (Russian mud corrosion). It delivers color and plating speed close to those obtained from hexavalent chromium electroplating baths, with improved deposit distribution. TriMac CP-200 can be used for sub-micron trivalent chromium plating of approximately 0.5 to 0.7 microns thickness. When measured to the Q-Color standard, it compares as follows to traditional bright chromium plate:trivalent chromium

Envirochrome

The original sulphate-based decorative trivalent chromium plating process. Envirochrome is extensively used in applications where the use of chromium trioxide-based decorative chromium solutions are prohibited. It is particularly suitable for most interior applications including automotive and plumbing. When measured to the Q-Color standard, it compares as follows to traditional bright chromium plate:trivalent chromium

twilite

The first trivalent chromium plating process to break from tradition. Twilite has been adopted worldwide as the dark trivalent chromium finish for interior and exterior applications. Twilite has a cool dark shade. When measured to the Q-Color standard, it compares as follows to traditional bright chromium plate:trivalent chrome plating process

starlite

Sulfate based dark trivalent chromium plating process. Starlite produces an attractive, lustrous dark chromium deposit usually on a bright or satin nickel deposit. Unlike many other dark inorganic coatings that generally have little inherent resistance to corrosion or abrasion it does not require a lacquer topcoat.Starlite trivalent chromium plating

Chloride Base Solutions

 

macrome cl3

MaCrome CL3 is a high speed trivalent chromium plating process and has a plating rate of more than 0.1μm per minute. It is specified by designers who require a finish which is both warmer and slightly darker than standard chromium. When measured to the Q-Color standard, it compares as follows to traditional bright chromium plate:trivalent plating

Galaxy

The darkest trivalent chromium plating process available; Galaxy opens an exciting new dimension in chromium finishing. Its color is described as warm and alluring. The corrosion resistance is excellent, so is suitable for exterior automotive applications. When measured to the Q-Color standard, it compares as follows to traditional bright chromium plate:trivalent chrome

ValueDescriptionGalaxy compared to standard bright chromium
