Liquid Paint/Wet Coating:
These coatings come in several colors and provide a uniform film thickness. Liquid coatings generally contain volatile organic compounds (VOCs). They are eliminated during the curing or baking process. When the VOCs are gone, the volume solids form a film on the extrusion.
Aluminum and aluminum alloys can be buffed, blasted, polished, ground, or sanded. These finishes can refine surface quality or prepare the aluminum for different cosmetic finishes.
Mechanical Finishes Techniques
A procedure used for improving the surface quality of extruded aluminum, this technique leaves behind a fine striation on the grinding direction. The surface finish results here will range from very fine and medium to coarse. Anodizing often follows surfaces that undergo grinding. Grinding before painting processes is useful in additionally enhancing the achievable surface finish.
Specific requests and requirements determine the smoothing of the aluminum surface, the gloss, and the quality of the polish. Polishing will often be followed by bright anodizing to achieve a high gloss finish. A polished character will typically also be anodized.
Known as barrel polishing and is mainly employed as a deburring action. Surface finishes will vary from matte to gloss, depending on the polishing medium applied to the drum.
Applying a pretreatment coat on the surface removes the aluminum cleaned with an alkaline or acidic solution. Following the cleaning, a pretreatment coating is used, enhancing powder or paint adhesion, and providing resistance against corrosion.
Have you ever seen aluminum extrusions that look like wood? The extrusions go through sublimation using a base coat of powder. After applying a base coat of powder, profiles can go through sublimation. Technicians then place a thin film with a pattern around the shape. The sublimation process directly transfers the wood pattern onto the extrusion. This method is rarely implemented but is becoming more common over time.
