Each powder manufacturer markets a variety of products with varying terms of guarantee and warranty conditions.
To create a simple classification for all powders manufactured internationally, the Qualicoat body has established 4 classes of powders.
The different classes require increased testing parameters as the Class number increases, as follows:
Class 1
minimum quality level for European regions
Class 1.5
minimum level for Australian region
Class 2
Higher durability powders
Class 3
Available for super-durable powders and cater for development for PVDF (fluorocarbon) powders
IMPORTANT NOTES:
Qualicoat Class 1.5 has been specifically established in agreement with Qualicoat for Australasian conditions. With advice from Dulux and Interpon, Qualicoat agreed that Class 1 rated powder would not have sufficient durability for the Australasian environment.
Class 3 is being introduced to provide testing parameters that are expected for the for new super-durable PVDF powders. These powders are only just beginning to be available in Europe, while Australia has had these products available for some years. They will now be submitted for testing.
Qualicoat separates the testing of powders into categories. These refer to finish type such as gloss, matt, etc. The full list of approved powders is available on the international Qualicoat website. When all Australasian powders are tested, Qualicoat licenced applicators will only be able to apply Qualicoat approved powders as part of their licensing requirements.
