Chrome Free Processes

These are silane / titanium / zirconium processes used for the treatment of aluminium to replace traditional chrome products.

Some of these processes are a drop in replacement for the chrome using a normal post rinse system.

Products are available containing polymer coatings which dry in place and do not require final rinsing.

These products are Qualicoat approved.

For further technical information on our product range please call Brian on 01204 495818 or email us to see which process meets your individual requirements.


A typical example would be Phosguard CP 304
This is a chrome free treatment for aluminium which produces a dry in place coating which does not require post rinsing.
