Methods comprising: (a) providing a coating composition comprising a fluoroacid compound of the general formula (I):XMFO&#x2003;&#x2003;(I)wherein each of q and r independently represents an integer of 1 to 10; each of p and s independently represents an integer from 0 to 10; X represents at least one cation selected from the group consisting of hydrogen, ammonium, alkaline earth metals and alkali metals; and M represents at least one element selected from the group consisting of Ti, Zr, Hf, Si, Sn, Al, Ge, and B; (b) contacting a metal substrate with the coating composition; and (c) adding to the coating composition a component selected from the group consisting of fluorine-free compounds of an element M, Group 2 metal compounds, Group 12 metal compounds, Group 13 compounds, Group 14 compounds, and combination thereof.

Metal treatment coating compositions, methods of treating metals therewith and coated metals prepared using the same

Cure accelerators for anaerobic curable compositions, such as adhesives and sealants, are provided, and which are defined with reference to the aromatic amides shown in structure I where R and R&#x2033; are each independently Calkyl, and R' is H or Calkyl or R and R&#x2032; together may form a four to seven membered ring fused to the benzene ring, and where R&#x2032;&#x2033; is optional, but when R&#x2032;&#x2033; is present, R&#x2032;&#x2033; is halogen, alkyl, alkenyl, cycloalkyl, hydroxyalkyl, hydroxyalkenyl, alkoxy, amino, alkylene- or alkenylene-ether, alkylene (meth)acrylate, carbonyl, carboxyl, nitroso, sulfonate, hydroxyl or haloalkyl.

Cure accelerators for anaerobic curable compositions

The corrosion resistance of a metal substrate surface treated with an acidic aqueous composition to form a conversion coating is improved by first contacting the surface with an oxidizing acidic pre-rinse, such as an aqueous solution of nitric acid and hydrogen peroxide, or nitric acid and hydrofluoric acid, or Fecations and hydrofluoric acid.

Process for treating metal surfaces

The invention provides anaerobic curable compositions, and methods of their production and use. These compositions provide excellent adhesion especially on oily surfaces.

Anaerobic curable compositions

In at least one aspect, the invention relates to an entirely or substantially chromium-free conversion coating composition and process for conversion coating metal surfaces that provides corrosion resistance. In at least another aspect, the present invention relates to an article having a metal surface that is at least partially coated with an entirely or substantially chromium-free conversion coating that provides corrosion resistance. In certain embodiments, the conversion coating composition comprises water and (A) dissolved fluorometallate anions selected from the group consisting of TiF , ZrF , HfF , SiF , AlF , GeF , SnF , BF , and mixtures thereof and (B) a water-soluble polymer which is a Mannich adduct of poly(4-vinyl phenol) and N-methyl ethanolamine. In other embodiments, the composition also comprises (C) a water-soluble polymer which is a Mannich adduct of poly(4-vinyl phenol) and N-methyl glucamine.
