Corrosion occurs due to high moisture, humidity or temperature and can be observed in the form of “white rust” – this will eventually lead to complete failure of the deposited coating and permit rusting of the underlying steel.
Passivated coatings increase the resistance of the zinc against this type of corrosion and therefore considerably increase the life of the base metal. A passivate will also allow a good bonding layer for paint, if paint is indeed required.
After your work is plated, you will need to passivate the deposit. At this point there are several options to choose from. The passivate chosen can provide varying degrees of protection but can also offer a coloured finish. Coloured finishes often give greater protection.
All of our passivates are formulated and manufactured by us and are exactly as you’d buy them as an industrial plater.
This is an amazing product that will quite literally add years to the life of your electroplated work. Our special formula lacquer can be used on copper, zinc, brass or cadmium and used at a range of dilutions. Can increase the protection by 10 times!
An environmentally safer alternative to a standard blue passivate, which contains no hexavalent chrome but instead is trivalent based. Used at 1 -
Please note that in Autumn of 2017, Chrome 6 containing products will be subject to stringent legislation changes and therefore we will not be supplying passivates with Chrome 6 as a base material. This includes the basic clear (blue), yellow and olive passivation products. Industrial users should contact us for more information.
PLEASE NOTE: Use of Chrome”6”products will now require licence -
Colour passivation may prove a little harder to attain -
