Low Gloss Finishes for Anodized Aluminum Trim

This paper explains the reflectance characteristics of anodized aluminum and describes the finishing treatments which produce the desired low glow appearance required by The Proposed Federal Motor Vehicles Safety Standards. Certain of these low gloss producing treatments are easily incorporated into existing finishing lines and in many cases are more economical to apply than the present bright specular finish. The materials and processes used to satisfy this proposed standard are discussed fully.
