How to apply Alodine 1200 on fuselage skin of aircraft


Dear Sirs,

We have a customer aircraft specified to use Alodine 1200 for surface treatment of their aircraft before applying subsequent primer and topcoat -- but they don't have the detail how to apply it. If you have this procedure please kindly recommend.

Best regards,

Mr. Manasak Thongkham

Alodine is a product of Henkel, Manasak, so you will be able to get a technical data sheet (as well as MSDS) from them. You may wish to review Mil-5541-F for an introduction to this chromate conversion / chem-filming process.

I would, however, be concerned about applying a process like this to an airplane skin without a thorough review of possible additional governing specifications. Good luck.

In the interest of saving time, we wish to install bonded inserts into Aluminum and Klegecell sandwich panels and then Alodine , prime and paint. Where can we find materials and processes to support this type of activity? Currently we cut a panel to size, edge fill, Alodine prime, and paint before we install our inserts.

My question concerns the availability of products and access to documentation on techniques used to mask inserts and ensure that Alodine can not pass into the cavities and areas around the inserts. We would also be interested in any opinion you may have on this subject and or references to studies on this same subject.

By the way your question is worded, it seems that you really aren't set up to handle the chromium wastes that you would generate with the application of Alodine 1200. If that is the case, you may want to look into a non-chromium product like Sol-Gel (AC-131). It works well as a pre-paint on aircraft skins and it has none of the environmental difficulties that Alodine 1200 has.

Are you trying to protect the cavity or the insert? Is this an immersion process, spray, or brush?
