QUALICOAT Update Standard

The QUALICOAT Standard for architectural powder coating is possibly one of the only quality standards applicable across the globe which is revised several times a year by the release of ‘update sheets’. The most up to date, 88 page QUALICOAT Standard, rewritten with all recent revisions, now dated 2021, is always freely available on the QUALICOAT website and details the stringent coating requirements for licence holders, including the requirement for twice yearly unannounced independent audits. No other architectural powder coating standard offers this level of quality.

Pure water for a perfect powder coat

Powder coating is going green. In some cases this is the result of legislation which requires existing process cleaning solutions to be replaced with more environmentally friendly ones. Increasingly, however, it’s coating quality that is the driver. Some coating specifications now demand salt spray testing for more than 1000 hours, and that means that surface preparation is absolutely critical. One of the proven ways of achieving high quality surface preparation is the use of pure water. Mains water contains a wide range of dissolved salts. These are harmless in drinking water but can promote corrosion and poor adhesion of powders to metal surfaces.

Powder Coat Failures and How to Avoid Them

Powder coating is applied in various plants across the UK using the well known methodology of spraying electrostatically charged fine polyester based powders onto a product rather than using a wet solvent or painting method. Products powder coated are then baked at an optimum temperature to melt the powder which allows it to flow, the product is then allowed to cool and the coating sets. The problem is, like most opaque coatings, whilst the finish looks good, any coating can hide a multitude of sins on the surface of the metal, the substrate, which will become evident over time.
