Abstract
Baked enamel coating system onto aluminum alloy is much used for building exterior and interior materials in Japan. However, it has been not yet discussed on the environmental management. Therefore, Japan Society for Finishing Technology has established a committee on the environmental management for baked enamel coating system onto aluminum alloy building materials. In this paper, it is discussed that the reserch theme is one of important bulding technological problems and an outline of pretest for surface preparation treatments before coating which has been studied at present.
