Detailed Product Description:
Alodine® 600RTU, a registered trademark of Henkel Surface Technologies, is a
pre-mixed, ready-to-use chemical formulation for a treatment process for aluminum
used to provide corrosion protection and as a surface preparation for paint and adhesives.
Sometimes called “aluminum passivation,” this formulation contains hexavalent
chromium and is intended to provide corrosion prevention even when left unpainted.
The primary difference between Alodine®600 and the more common 1200, 1200S, and
1201 formulations is in coating weight. Generally, the Alodine®600 formulation
will produce a lighter weight film than the 1200. The Aerospace industry typically
uses the 600 formulation on areas that require electrical bonding, whereas the
Alodine 1200 series (1201, or 1200S) are called out where maximum corrosion
protection is required for surfaces to be painted or left unpainted.
For aviation applications, Alodine®600RTU is used for corrosion protection where
low electrical resistance is required. The subsequent exposed electrically bonded
assemblies or installations must then be sealed.
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.
Specification & Certifications:
Alodine® 600RTU methods and properties produce results consistent with those
defined by Mil-C-5541-F, Mil-DTL-81706, and referenced in QPL-81706-16.
Application Notes & Surface Preparation:
This is a visible coating that leaves the surface with a golden coloration.
Please refer to Henkel’s “Technical Process Bulletin #236705 (see link below) for proper
application and use.
Comes packed in ˝-Pint, 1-Pint, 1-Quart, 1-Gallon, or 5-Gallon HDPE containers.
