Yellow Chromate Concentrate - Cadmium Look

Yellow Chromate


After preparing the part to accept the process, the part is simply dipped into a solution for a few minutes. The zinc & the chromate react to form the new colors. To improve those older zinc (pot metal) castings, plate with a fresh zinc plate before chromating.

Steel parts that have previously been plated with zinc can be chromated with no further pretreatment. Zinc alloy die cast parts may be surface activated by immersion in a weak acid. Full operating instructions are in the manual. The Blackener provides a deep black finish, similar to a Black Oxide, but with much better corrosion resistance

The Yellow Chromate is a yellow/bronze iridescent finish on plated cadmium and zinc.

Liquid concentrate is used at 0.5% to 3% by volume in water at 18° to 33°C. The finish has outstanding resistance to salt spray, greatly surpasses the normal 96 hour salt spray resistance specified for yellow chromates on zinc. It will withstand up to 200 hours salt spray. The deposit is a pleasing finish in itself. It is an excellent base for paint. The finish may be dyed to various colors.

Supplied as 120mL solution and will make up to 15 litres of working solution.

Our preferred method is to use only half of the solution to make up 8 litres of working solution which then allows for additions of the chromate solution to be added to darken the colour. Additions can also then be made as the solution weakens because of use.

Parts must be immersed for up to  1 minute, depending on depth of colour,

Rinse in fresh water to stop darkening process.

Dry with hot air [hairdryer].
