QUALICOAT Specification Update
Companies that form the membership of QUALICOAT recognise that the association is constantly updating its powder coating standard for architectural aluminium installations. Irrespective of country borders, the standard is recognised across the globe for specification of high quality powder coat applications for architectural use. Updates to the current standard, now in its 16th edition, are issued to licence holders who immediately implement the changes to the processes. The constantly reviewed QUALICOAT Standard differs to typical country specific standards, such as British Standards and European Standards, that usually only get reviewed once every few years.
The 16th edition of the QUALICOAT Standard launched in early 2019 was updated early in 2020 to incorporate the 2019 updates. A further four updates were announced on the 1st July 2020 which now forms an appendix to the current standard.
With membership of the QUALICOAT association comes communication and all new updates are discussed during member meetings prior to implementation into the standard giving members the opportunity to question and prepare for changes in production. Three of the recent updates relate to changes in production testing conducted in powder coating applicators laboratories and the fourth one related to approval of colours for Class 3 powders.
The first of the production update sheets, ‘US10’, effective immediately, removes the ‘cupping test’ from the production line tests used during powder coat application. This test now replicates some of the existing tests carried out on production sample plates and following the guidance from the ‘In-house Control Working Group’ it was felt this test could be eliminated. Update sheet ‘US11’, effective immediately, refers to minor corrections in the standard and to maintain correct cross reference to emerging national standards and charts. Update sheet ‘US12’, effective from 1st January 2021, highlights small but crucial changes in frequency of production testing proposed by the ‘In-House Control Working Group’.
Update Sheet ‘US13’, effective from 1st January 2021, defines which RAL colours are to be tested to meet the Class 3 powders standard and lists the RAL colours, that as powder coating technology stands today, do not have sufficient resistance to colour change after ten years of outdoor exposure to ‘Florida Outdoor Exposure Testing’. QUALICOAT Class 3 powders are the most resilient powders available for powder coating, sometimes known as ‘Hyper- Durable Fluorocarbon Powders’ and are used in areas of the world where exceptional resistance to UV degradation and abrasion is required. In the UK Class 1 powders are commonly used for general applications and many new prestigious projects are being specified in Class 2 powders for extended durability on both colour fastness and gloss retention.
Copies of the sixteenth edition of the QUALICOAT Standard, complete with the amended updates mentioned, are available through the UK Association website, www.qualicoatuki.org together with an up-to-date list of licensed UK and Ireland Powder Suppliers, Pretreatment Suppliers and Applicators.
