NEW FORMULA - Please read label carefully.
Yellow Chromate
PART NUMBER:- YCHR12
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 0.1% by volume in water at 21° to 38°C.
To make a new solution add bottle of concentrate, 125mL to 12.5 litres of distilled or de-ionised water.
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.

SAFETY AND HANDELING
Yellow Chromate is highly toxic and acidic and therefore protective clothing including face shield, gloves and overalls are recommended when handling.
Any splashes should be rinsed immediately with clean water.
Medical attention should be sought as soon as possible. Yellow Chromate is an oxidising agent and any contact with combustible organic materials should be avoided.
