Passivates / Chromates

Detailed Passivates/Chromates Information

CHROMATES

Chromates are used in order to coat metal parts to provide a longer life for the part. Chromating is commonly performed on zinc-plated parts to make them more durable. The chromate coating acts like paint, protecting the zinc from corrosion, this can make the part several times more durable depending on chromate layer thickness. Chromates can come in many different colour variations: clear, blue, yellow or black.

Jane Kits offers two chromates in blue and yellow variations. They are referred to as Gold Bright and Blue Dip. These chromates are trivalent chromium chromates and therefore have an extremely lower toxicity to the traditional hexavalent chromium that was traditionally used. Gold Bright is a traditional yellow chromate that is commonly found in many automotive and construction industries. Blue Dip is a trivalent chromate conversion coating for zinc. It imparts a clear blue coating with no evidence of yellowing. Both of these chromates are included in our Zinc Plating Kits or can be purchased individually in various sizes via our website.

Both of these chromates are very concentrated and will need to be mixed with water at a ratio of 15 ml of chromate per 1 litre water. Therefore 60 ml of chromate will make 4 litres of plating chemical.

It is a simple dip process and does not require any electrical current or complicated bath set up. The procedure is straight forward and needs to be done immediately after parts have been zinc plated. Following the zinc plating procedure the parts continue through a cleansing and activation process. The activation chemicals required for this procedure is called Metex IT. This is essential for good adhesion of the chromate. The parts are immersed into the chromate solution and left for the correct time.

NOTE only use deionised, demineralised, distilled or rain water to create your plating bath. Do not use tap water. It may have too many additives that will contaminate your bath.

METEX IT ACTIVATOR

METEX IT is a dry acid material that is mixed with water. This is used as a pre-dip activator before passivating. It will improve the appearance of the passivating, enhance the adhesion and lengthen the life of the passivating solution. The Metex IT is mixed at a ratio of approx 20 grams per Litre and dip for 30 seconds.

METEX IT Activator 100 grams – $5.00

About Us

The Jane Kits story began when John, a vintage motorbike restorer realised that it would be much more convenient and economical if he was able to plate his own parts in the home workshop. So John decided to source and create his own plating kit and hence Jane Kits was born. John went on to receive numerous awards for his meticulously restored bikes with parts plated using his ingenious new kit.
