Metallic powder coating finishes are like solid tone finishes, but with metal flake added for sheen and sparkle. The color of the metallic flake varies from powder to powder. Overall, they are relatively easy to spray, but in some cases may require a slightly more honed spraying technique to keep the finish even. Metallic powder coating which has a metallic or sparkle effect added to them. These metallic pigments are usually aluminum flake or mica and can be different colors and sizes. There are those that will be very obviously sparkly or glittery, others shimmery, and some will have more subtle sparkle effects. So, for this guide, we should specify that we aren't talking about coatings that give the appearance of metal - what we are talking about are metallic coatings that have a sparkling effect.
Metallic powder coating is formulated to meet color standards, i.e. The RAL standard. Despite the stringent quality control measures exercised during production, a complete batch-to-batch consistency cannot be guaranteed. Upon request the manufacturer therefore supplies production panels of individual batches. Batch to batch consistency is comparable to that of non-metallic powder coatings. However, application process and equipment also are a factor in the final color/effect of the coating. An acceptance test must be performed on the actual application equipment before processing. Those color/effect variables, particularly when powder is recycled, must first be established by producing an upper and lower tolerance sample. To largely eliminate color/effect differences caused by the coating system, an entire coating job must be processed on the same coating line, without parameter fluctuations, preferably without interruptions and with consistent recycling percentages. Manual coating is likely to produce variations of color and/or effect due to inconsistent film thickness. Manual coating must therefore be adjusted to automatic processing with respect to color and effect. Coating thickness is of importance, as variations will cause color/effect differences.
TYPES
Bonded - Bonded metallics are coatings in which the effect pigments (the metallic or mica flakes) adhere to the powder coating particles. Doing this creates a more consistent application, as opposed to dry blend/unbonded, and enables a much better performance once reclaimed.
Unbonded - As you may guess from the name, unbonded metallics are powders that have not been put through the bonding process. Rather than that, the metallic flake and the powder are put into what is, essentially, a blender. That is whizzed around and boxed up. It is a simpler, speedier, and cheaper process as opposed to what is used to create bonded metallics. While that may sound ideal, let's go through the advantages and disadvantages first.
