Detailed Product Description:

 

Alodine® 1500 is highly concentrated and is used to make-up large immersion

 

baths. A gallon of Alodine® 1500 will make a 100-gallon immersion bath.

 

 

 

 

This is a clear conversion coating. As with the more common Alodine® 1001,

 

Alodine® 1500, is also 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. 

 

 

 

 

Like 1001, Alodine® 1500 is used when a silver-white aluminum appearance is

 

desired instead of the more typical gold color of the Alodine 1201 finish.

 

 

 

 

Chromate conversion is an excellent treatment method to prep aluminum prior to paint

 

or adhesives since it greatly enhances the ability of an organic coating to form a bond

 

with the aluminum substrate. Being a surface conversion treatment rather than a coating,

 

it will not alter the dimensions of the part.

 

 

 

 

It is frequently used on electrical and electronic equipment because it provides increased

 

corrosion resistance while remaining electrically conductive. 

 

 

 

 

The Alodine process produces a microscopic thin film commonly prescribed on aluminum

 

to provide the following surface characteristics:

 

  • High-adhesion surface preparation for paint

     

  • Improves corrosion resistance

     

  • Preserves electrical conductivity of surface

     

  • No change in dimensions

     

 

 

 

Specification & Certifications:

 

Alodine® 1500 methods and properties are defined by Mil-C-5541-F (Now AMS-C-5541)

 

and AMS-A-2473.  This product is listed on QPL-81706 as certified for Class 3.

 

 

 

 

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. 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.

 

 

 

 

Applications in which temperatures can reach over 120ºF can break down the corrosion resistance

 

of the coating. In comparison to anodizing, this chemical film is more fragile and

 

not generally recommended for high-use areas.

 

 

 

 

Surface Preparation:

 

Aluminum surfaces must be cleaned with a suitable etchant such as Alumiprep 33

 

or Metal Prep 79, followed by a water rinse.

 

 

 

 

Immersion Process:

 

To formulate bath, mix 1part Alodine® 1500 concentrate with 99 parts of

 

water. Immersion time is 2 to 5 minutes. Application temperature can range

 

from ambient up to 100ºF. Rinse part thoroughly with water and allow to dry

 

for about 24 hours, after which, surface is ready for paint.
