Detailed Product Description:

Henkel Alodine^®1200S is a highly concentrated powdered chemical composition

used to create immersion baths for application of a protective conversion coating

on aluminum surfaces.

Background:

Alodine^® is a registered trademark of Henkel Surface Technologies and is a chemical

treatment process for aluminum used to provide corrosion protection and as a surface

preparation for paint and adhesives. Sometimes called “aluminum passivation,” it

contains hexavalent chromium and is intended to provide corrosion prevention even

when left unpainted.

Specification & Certifications:

Alodine^®1200 methods and properties are defined in Mil-C-5541-F (NowAMS-C-5541)

and AMS-A-2473. Additionally, Alodine^® 1200S is listed on the Qualified Products List,

QPL-81706.

Application Notes:

The best results are achieved on wrought alloys (machined billet aluminum alloys).

Good results can also be achieved on type 356 aluminum castings. Type 380 die

casting alloys do not alodine well, however. It should also be noted that the

chemical film is fragile immediately after processing and a 24-hour waiting time

before handling the parts is preferable.

This is a visible coating that leaves the surface with a coloration ranging from a light

Iridescent gold to tan depending upon alloy and immersion time.

Surface Preparation:

Consult Henkel “Technical Process Bulletin #0980” (see link below) for recommended

surface preparation.

Immersion Process:

Consult Henkel “Technical Process Bulletin #0980” (see link below) for recommended
