1. Specification for the pre-treatment, powder organic coating and stoving of metal piece parts.

1 .2 This specification states the requirements for all items which require Powder Organic coating (Powder Coating).

Pre-treatment refers to the treatment of metal surfaces, after cleaning and prior to applying the final finish, to retard corrosion of the base metal.

2.1 Aluminium Alloy Castings

Aluminium castings are treated with a '9' stage Chromate Conversion, as recommended by the chemical manufacturer.

Pre-Treatment Process

The following chemical process tanks for treating

Pre-Treatment

The following chemical process tanks for treating

All mild steel piece parts which have been Electrophoretic Painted (E Coated) will be in accordance with specifications and cleaned of any form of contamination before powder coating.

The cleaning method used will not be detrimental to the E Coat or to the end product.

2.5 3 CR 12 Stainless Steel Parts

3 CR 1 2 Stainless steel parts will be pre-treated in accordance with the following processes:
