A method according to claim 2 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.
However, preferably the surface is not treated with any non-mercapto-substituted silanes, silicates, chromates or other conversion coatings prior to treatment with the mercapto-substituted silane. Aluminum and aluminum alloys can be effectively etched using strongly acidic or strongly basic solutions. 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.
Mercapto-substituted silanes, such as gamma-mercaptopropyltrimethoxy silane, may not be soluble in water alone to the extent necessary to practice this invention effectively. Hopefully you can identify the vendor and the vendor is still around.
TDS – MSDS
Osoprep composition of the mercapto-substituted silane treatment solution and the corrosion resistance results are given below in Table I.
In addition, when polymer coatings such as paints, adhesives or sealants are applied to the metal, corrosion of the underlying metal may cause a loss of adhesion between the polymer coating and the base metal. Mercapto-Substituted Silane Treatment 1 room temp.
These adhesion procedures usually include a cross-hatch tape test whereby the organic coating is cut in a specified cross-cut pattern and tape is applied and removed to determine the quantity, if any, of the mdss coating that is removed.
Metallic coated steel having a siloxane film providing temporary corrosion protection and method therefor.
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. Preferably, the metal surfaces are cleaned and etched prior to treatment with the process of this invention. 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.
The inventors have found that an aqueous solution of ethylene glycol monobutyl ether does an excellent job of solubilizing the mercapto-substituted silane and leaves behind a spot free finish as it evaporates from the treated surface.
A 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. Water Rinse 1 room temp. A method according to claim 6 wherein isorep solvent is ethylene glycol monobutyl ether.
This potential instability can be controlled by increasing the concentration of solvent in the treatment solution before, or at the first sign of cloudiness. Leung et al, J.
I am looking for information on the following chemicals, what are they used for, who mfg’s or sells them, what are their dangers:. 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.
I believe it is a cleaner. Please contact them for this product. It is another object of this invention to provide a treatment for metals which improves the adhesion of subsequent organic coatings to the metal while at the same time improving the corrosion resistance of the metal.
Metal sheet with enhanced corrosion isoprrp having a silane treated aluminate coating.
Keohan et al, Annu. I’m stretching my memory on the DWbut believe thats a hexavalent chromate conversion coating we used many years ago Gamma-mercaptopropyltrimethoxy silane is available from the Witco Corporation of Greenwich, Conn.
Environment-friendly nano water-based silane treatment agent capable of improving anti-corrosion performance of metal surface.
ISOPREP by MACDERMID INC Material Safety Data Sheet #CGLCZ.
A method according to claim 1 wherein the metal is selected from the group consisting of aluminum and aluminum alloys. After curing, the treatment with the mercapto-substituted silane may be repeated and baked again, as desired. There are several sheets iso;rep, so use the search engine and pick the most relevant data. Thus, there remains a need for a simple, low cost, effective technique for inhibiting corrosion of metals, particularly for aluminum and aluminum alloys.
In addition, excellent adhesion of organic coatings to the treated metal surfaces can be achieved with the process of this invention.
