In this regard, a storage stable concentrate of mercapto-substituted silane can be prepared by dissolving the silane in a solvent, such as ethylene glycol monobutyl ether, without water.
Metallic coated steel having a siloxane film providing temporary corrosion protection and method therefor. Metal sheet with enhanced corrosion resistance having a silane treated aluminate coating.
The concentration of mercapto-substituted silane may range from 0. I’m stretching my memory on the DWbut believe thats a hexavalent chromate conversion coating we used many years ago For cleaning the surfaces of aluminum and aluminum alloys, both acid and alkali based cleaners are available. A method according to claim 1 wherein the mercapto-substituted silane is a multifunctional mercapto-substituted silane ksds the following chemical structure: Keohan et al, Annu.
The treatment solution is applied to the metal surfaces by immersion, spraying, flooding or other similar means of isoprrep.
Wherein R 1R 2 and R 3 are independently selected from the group comprising of alkoxy groups, alkyl groups and hydrogen, and wherein n is an integer from 0 to Matienzo et al, J.
These aluminum cleaners are nsds relatively weakly basic or acidic in comparison to the etchants.

The concentration of mercapto-substituted silane in the treatment solution may be from 0. Although the inventors have found that treatment of the metal with a cleaner and an etchant prior to treatment with the mercapto-substituted silane of this invention generally improves the corrosion resistance provided by the process, the best choice of cleaners and etchants may depend upon the metal being treated.
A method according to claim 6 wherein the concentration of the mercapto-substituted silane in the treatment solution is from 0.
Each sample was then processed in a salt spray chamber according to the procedures set forth in ASTM B standard in order to determine corrosion resistance.
Once the mercapto-substituted silane is applied to the metal surface the treated metal should be baked in order to dry and cure the coating. As a result, prior preparation of the surface will generally yield better corrosion resistance results after treatment with the process of this invention.
Recently, various techniques for eliminating the use of chromates in corrosion inhibition and adhesion promotion treatments have been proposed.
Military specification MIL-CD provides specific procedures for measuring the corrosion resistance of a treated part. A method according to claim 2 wherein the metal is selected from the group consisting of aluminum and aluminum alloys. Please contact them for this product. Many of the foregoing proposed techniques, however, have been proven to be ineffective, or to require time consuming, energy inefficient, multi-step processes.
As the silane becomes hydrolyzed by the water it will have a tendency to precipitate and the solution will begin to take on a white cloudy appearance. The inventors have found that treating aluminum or aluminum alloys with the mercapto-substituted silane containing composition of this invention provides both increased corrosion resistance and enhanced adhesion of subsequent organic coatings to the treated surface.
Method of treating metals using amino silanes and multi-silyl-functional silanes in admixture.
Preferably, the treatment solution is an aqueous mixture of the mercapto-substituted silane and selected solvents. Beccaria et al, Corros. It is believed that this instability may also osoprep from the polymerization of the silane molecules in the solution to form 2 or 3 member chains. Treatment of the metal surfaces with the composition of this invention inhibits corrosion of that surface and also improves adhesion of subsequent organic coatings to the treated surface.
Aluminum alloys, in particular, can be susceptible to corrosion since the alloying elements used to improve the metal’s mechanical properties may decrease corrosion resistance.
Isoprsp method according to claim 1 wherein the metal is subjected to a process selected from the group consisting of cleaning, deoxidizing, etching and a combination of the foregoing, prior to contacting the metal with the treatment solution. A variety of known cleaners, deoxidizers and etchants may be employed for this purpose, with the appropriate choice being made with the specific metal surface to be prepared in mind.
A loss of adhesion between the polymer coating and the base metal may similarly lead to corrosion of the metal. The compositions and methods of this invention are particularly suitable for treating aluminum and aluminum alloys. Acetic acid can be used to make any needed adjustments to pH.

Prior art techniques for improving corrosion resistance of metals widely employ the use of chromate conversation coatings to passivate the surface. CA CAC en In this regard, atmospheric corrosion is of particular concern. It is an object of this invention to provide an improved method of inhibiting corrosion of metals, especially aluminum and aluminum alloys, which is simple to apply, cost effective and environmentally friendly. Specifications for testing the effectiveness of the corrosion inhibition and adhesion promotion of various treatments have been established.
