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

 

coating process sequence and parameters. 

 

 

Precautions:

immersion bath.  Read and understand the MSDS, downloadable below before using this

 

chemical.
