There are only two main reasons to coat aluminum extrusions. The first is to control the appearance for color coordination, uniformity, or visual appeal. Secondly, to protect it. The type of aluminum coating selected depends upon a product's end-use and market preferences. In some instances, no coating is required at all. But when there is a requirement, liquid paint or powder coating can be applied.
Powder coating is one of the most prominent finishing methods. After the proper amount of powder is applied, the profile is baked in an oven where the powder particles are melted to a liquid state, fusing together to form a film.
Liquid coatings are fluid materials that, when applied to a surface, form an adhering film to protect and beautify the substrate.
Although there are significant differences between liquid and powder coatings, both perform two essential functions – cosmetic and protective. If your products require this type of finishing, give us a call today to see how we can assist you.
