Overview of Performance of Anodic Oxide Film and Polymer Coatings

  Aluminium profile and their alloy products have a series of excellent chemical, physical, mechanical, processing properties and characteristics, which enables the rapid development of the Aluminum extrusion profile industry. In the process of social and economic development, Aluminium construction profiles are usd in vriuos industries. Surface treatment technology enables aluminum and its alloys to achieve better surface properties, not only improving and enhancing the physical and chemical properties of aluminum, such as corrosion resistance, chemical resistance, wear resistance and other surface features, but also endowing aluminum surfaces with various colors, greatly enhancing the surface decoration of aluminum. Aluminum surface treatment films can be classified from various perspectives according to production processes,, such as anodized films, electrostatic powder coating films, electrophoretic coating films, etc., and classified according to film layer materials, such as aluminum anodization films, fluorocarbon paint films, etc.
