scope:
This specification covers the requirements for the chemical materials used in the formation of conversion coating by the reaction of the material and the surfaces of aluminum and aluminum alloys.
The materials, capable of forming protective coatings by chemical reaction with aluminum and aluminum alloys, shall be of the following classes, as specified (see 6.2 and 6.3.1).
Class 1A - For maximum protection against corrosion, painted or unpainted. Class 3 - For protection against corrosion where low electrical resistance is required.
Conversion coating materials shall be of the following forms for application by the methods as specified (see 6. 2 and 6.3.1).
Form I - Concentrated liquid Form II - Powder Form III - Premixed liquid (ready for use touch-up brush application)
Method A - Spray Method B - Brush Method C - Immersion
intended Use:
Class 1A materials covered by this specification are intended for use in the formation of chemical conversion coatings which are corrosion preventive and will improve adhesion of paint finish... View More
