As opposed to powder coating, wet coating for aluminum extrusions includes acrylics, polyesters, siliconized polyesters, and fluoropolymers. After the paint is applied, they are baked or cured similar to powder coating to seal the finish.
Wet paint finishes are typically smoother than powder coating and provide similar protection to the elements, while typically exhibiting more vibrant metallic covers that pop.
Powder coating refers to the process of applying fine particles of a resin in a variety of colors to aluminum surfaces. This resin powder is applied to the material through the use of an electrostatically-charged spray gun that allows the powder to bond to the receiving material.
Once the product is coated in the dry resin powder, the finish is cured in a large industrial oven that allows the powder to imbue itself to the metal. This creates a uniform, thick and durable finish. Powder coating is available in the full spectrum of color and gives the material additional resistant to chemicals, UV Rays, and cracking or chipping.
