Various Texture Paint Development Services

As the professional manufacturer, we would like to provide you Various Texture Paint Development Services. Alodine, the trade name for chromate conversion coating, is also known as chemical film. It is a thin coating used to passivate aluminum. The chemical baths used to apply the coating are often made with proprietary formulas, but all use chromium as the primary ingredient. When you request Alodine for a machined part, you may see that the process meets the MIL-DTL-5541F specification, which refers to the U.S. Military Specification for Chemical Conversion Coatings on Aluminum and Aluminum Alloys.

Alodine's protective layer acts as a corrosion inhibitor and improves the adhesion of paints and adhesives, so it can be used in conjunction with decorative topcoats. Alodine also allows aluminum to maintain its thermal and electrical conductivity, which other finishes can reduce. The color can be clear, gold, yellow, or tan, depending on the specific product used.

Difference between Surface Finish and Surface Finishing

Surface Finish: Surfaces have characteristics resulting from the manufacturing process: roughness, asperity, and waviness. Each of these is a "surface finish," and basically they quantify how irregular the surface is (on a microscopic scale). Depending on the function of your product, you may want to set specific values for these characteristics.

Surface Treatment: This term covers processes that protect and improve the appearance of a surface. Some of these processes add material, some remove material, and some use heat, electricity, or chemicals to change the surface finish of a part. This article will take a closer look at these processes with the goal of helping you choose the best one for your project.
