Durability of Surface Treated Aluminum Building Materials

Part 2 Estimate by the Actusl Situation of Anodic Oxide Film and Combined Coating of Anodic Oxide and organic Films

Abstract

There is a report in 1987 about durability of surface treated aluminum building materials.Now we are having many results used for 20 years or more.So we reviewed the durability by the actual situation.The durability of the anodic oxide film were assumed to be 10 years,and combined coating film of anodic oxide and organic films were assumed to be 20 years.
