It compares favorably with the hexavalent coatings providing a conversion coating that fulfills the corrosion, paint and electrical requirements of the different specifications. The materials are classified according to its coating thickness: It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Thank you for your answer. Class 3- Clear For protection against corrosion where low electrical resistance is required.

Chromate conversion coatings are normally applied by dipping: ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date. This specification covers the requirements relating to rinsed and non rinsed chromate conversion coatings on aluminum and aluminum alloys intended to give protection against corrosion and as a base for other coatings.

We test coating wt. Class 1; Class 2; Class 3; and Class 4. This specification covers the requirements relating to rinsed and non rinsed chromate conversion coatings on aluminum and aluminum alloys intended to give protection against corrosion and as a base for other coatings.

Thank you for your answer. I can vouch that their pdf delivery works well at least on my computer, it did Class 1; Class 2; Class 3; and Class 4. Class 1A- Yellow For maximum protection against corrosion, painted or unpainted. I can vouch that their pdf delivery works well at least on my computer, it did Class 1A- Clear For maximum protection against corrosion, painted or unpainted.

Both Hexavalent and Trivalent films at Advanced Surface Technologies have passed initial hour salt spray testing and are subject to monthly hour salt spray testing as well as paint adhesion testing conforming to all specifications. Chromate provides excellent corrosion resistance, is conductive and results in no measurable buildup 0.

ASTM B Spec for Chromating Aluminum

It is asstm used for an undercoat for paint or adhesive applications due to the excellent bonding properties it provides. But even if you do, I’d suggest that you not certify compliance to a spec you don’t have on hand.

Class 1A- Clear For maximum protection against corrosion, painted or unpainted.

Chromate Conversion Coating

Chromate Conversion Coating also commonly referred to as Chemical Film, Chem Film, Alodine or Iridite converts the surface properties of the substrate typically aluminum or magnesium as compared to plating which applies a coating onto the surface of the substrate. Your Metal Finishing Solution. Chromate conversion coatings are the most widely used coating for corrosion protection of Aluminum and Aluminum alloys minimizing surface oxidation.
