AppendicesA4 – Definition of metallic powder coatingsMetallic powder coatings are powder coatings with a metallic or metallized effect. A metallic powdercoating is a "normal" powder coating, the difference is the pigmentation. Powder manufacturersachieve this special effect by incorporating metal (<strong>for</strong> example: leafing or non-leafing aluminium) orother materials (<strong>for</strong> example: mica) in the <strong>for</strong>mulation of the powder.We can separate metallic powder coatings into two categories:• One-coat systems with a metallized appearance (no clear coat is needed <strong>for</strong> good outdoordurability <strong>and</strong> resistance). The current approvals are sufficient.• Two-coat systems: metallic powder coatings that need a clear coat in order to have acceptableweathering resistance. These specific two-coat systems must be approved separately byQUALICOAT.The powder manufacturers are responsible <strong>for</strong> advising their customers whether they need to use atwo-coat system or not.11 th Edition - 55 - APPENDIX 4
