Aluminum Powder Coating - Aluminum powder coating is a process that enhances the durability, appearance, and corrosion resistance of aluminum surfaces. It’s widely used for both decorative and protective purposes in industries ranging from automotive and construction to furniture and electronics. Here’s an overview of the process, benefits, and key considerations: *. Process 1. Surface Preparation: The aluminum is cleaned, often through a process like sandblasting or chemical pretreatment, to remove any contaminants, oxidation, or oils. This ensures good adhesion of the coating. 2. Powder Application: A dry powder—usually polyester, epoxy, or polyurethane-based—is electrostatically applied to the aluminum surface. The charged particles of the powder adhere to the metal. 3. Curing: The coated aluminum is then heated in an oven at around 200°C (390°F), which melts the powder, creating a smooth, durable finish. #Aluminum Powder Coating Manufacturing.
