We carried out a joint experiment on "Modification Method of Metal
Surface" with Agency of Industrial Science/Technology and LAN Technical
Services Co., Ltd, and completed registration for patent on November 10,
2000.
With regard to the metal surface processing, there still remains a lot of things unknown and we can expect much in this field.

-
 Purpose
- To provide a method to modify the surfaces of aluminum, aluminum alloys, stainless steel, galvanized iron and tin in order to improve adhesion power of paints and better contacting power of adhesives.
- To present a method, in addition to the above, to implement such modifications easily without post-treatments and bad influences to processed forms even in precision processing applied on metal surfaces.
- Composition
- UV radiations containing 253.7nm or 184.9nm and 253.7nm are applied to the surfaces of aluminum, aluminum alloys, stainless steel, galvanized iron or tin, which are followed by painting, adhering and so forth.
