Frequently Asked Questions about Qualicoat.

Superior Paint and Powder Coating are Qualicoat members. Qualicoat is the leading organisation for creating specifications and standards for the correct application of polyester powder in architectural applications.

When we receive an order to treat, colour and protect architectural aluminium, we adhere to the strict standards and specifications laid out by Qualicoat.

What is the Qualicoat guide to power coating aluminium?

Polyester powder coating extends to much more than just windows and doors. However, the coating of architectural aluminium extrusions forms a substantial part of our business. We give an explanation of the various standards applicable when we receive your material for polyester powder coating.

Where does the Qualicoat Standard apply?

The Qualicoat standard covers the vast majority of aluminium extrusions used for architectural applications. Examples include window frames, doors, curtain walling, powder coated metal railings, panels, pressings, louvres and many other applications.

Why are Qualicoat and other standards necessary?

The Qualicoat standard helps architects and building designers choose the correct specification for any powder coated aluminium. The intention is that meeting a high standard ensure that any aluminium products stand the test of time and provide the maximum value to building owners and occupiers.

Why do we even need standards for powder coating aluminium?

It is important to remember that the powder coating process has been used in the UK for over forty years. During this time, powder manufacturers and applicators have learned a lot about how early powder coated frames have lasted in commercial and residential environments. Standards, processes, quality and methods of application has been improved consistently. Qualicoat has been a major force in creating high standards for powder coating businesses such as Superior Paint and Powder Coating.

What is the Qualicoat Approved Powder Coating Process?

Qualicoat standards work to ensure that powder coated finishes provide protection for a building window or curtain walling frame. It is the many processes involved that ensure the powder does not fail. Experience has shown that incorrect pre-treatment is often the cause of problems rather than the failure of the powder finish itself.

Pretreatment is necessary to ensure that aluminium extrusions are suitably cleaned and de-greased ready to receive the polyester powder. Pretreatment also ensures the powder bonds and seals to the aluminium and offers the right key surface for the powder to adhere correctly.

What standards apply with Qualicoat?

British and European Standards are used. These are BS EN 12206-1:2004
‘Paints and varnishes – Coating of aluminium and aluminium alloys for architectural purposes’

The previous standard that was in use for many years was BS 6496:1984.

The Qualicoat Standard encompasses the latest BS EN 12206-1:2004 in its entirety.

How does someone become Qualicoat Approved?

To become an applicator to the Qualicoat standard, a process of vetting and inspection is carried out. Superior Paint and Powder Coating are regularly inspected to ensure we continue to meet the high standards set out by Qualicoat.

How do I specify Qualicoat approved polyester powder coating?

If you are an architect preparing a building specification the following clause should be included.

Architectural powder coating to Qualicoat standard from approved supplier.

For projects in severe environments such as the seaside there is a ‘Seaside’ class powder coating process.  This is a more intensive pre-treatment and finishing method.  It can be specified as follows:

Architectural powder coating to Qualicoat ‘Seaside’ standard from approved supplier.
