One of the great things about powder coating is that it can be used on a wide variety of materials. However, some materials present more challenges during the powder coating process than others. Aluminum, for example, can be difficult to work with. Fortunately, we at Reliance Finishing have the knowledge and skills required to avoid the potential pitfalls of powder coating aluminum.
One problem people occasionally run across with powder coating on aluminum is peeling. As a general rule, powder coating should not peel, so if it does, you know that something has gone wrong during the coating process.
When the powder coating on an aluminum surface starts to peel, it is because of corrosion underneath the powder coating. This type of corrosion, and the effect it has on powder coating, can be avoided with proper pretreatment. At Reliance Finishing, we know exactly how to clean and prepare aluminum in a way that will prevent corrosion, and by extension, peeling.
Another challenge that applying powder coating to aluminum can present is adhesion failure. Adhesion failure during powder coating application is relatively rare, but it can happen, and is typically a result of improper application or failure during the pretreatment process.
Our team at Reliance Finishing is trained in proper pretreatment and application procedures that help prevent adhesion failure when using powder coating on aluminum.
It is not uncommon for powder coated aluminum to suffer color inconsistencies. Such color inconsistencies are most likely to occur when powder coatings made by two different manufacturers are used on the same piece during different jobs. At Reliance Finishing, we are aware of this issue, and take the necessary steps to color match appropriately.
