Method for preventing filiform corrosion of aluminum wheels

摘要

Bright, non-anodized aluminum wheel covers and other like trim on automobiles subject to the disfiguring effects of filiform corrosion are given prolonged life by the protection of a powder coating containing a UV absorber, a light stabilizer or mixture thereof, and a small amount of an epoxy resin which does not lessen the weatherability of the coating. The powder composition is baked on to give a clear coating.
