scope:

This specification covers the requirements for two classes of chemical conversion coatings formed by the reaction of chemical conversion materials and the surfaces of aluminum and aluminum alloys. This specification is intended specifically to provide components of military weapon systems with maximum corrosion resistance. The coating also provides a surface having better paint adhesion than uncoated aluminum. It is not intended as a general purpose coating for commercial and decorative applications, (see 6.1).

The chemical conversion coatings shall be of the following classes, as specified (see 6.2).

Class 1 A - For maximum protection against corrosion, for surfaces to be painted or left unpainted, (see 6.1.1). Class 3 - For protection against corrosion where lower electrical resistance is required, (see 6.1.2).

intended Use:

Class 1A chemical conversion coatings are intended to provide corrosion prevention when left unpainted as well as to improve adhesion of paint finish systems on aluminum and aluminum alloys.... View More
