PASS 0.0064 Procedure for prior treatment or / and coating of metallic surfaces before conformation with a similar coating to a varnish, and use of substrates covered as such. It is preferred that the compositions be as free as possible of alkali metals, since these tend to promote corrosion. Contacting of the metal surface may be performed by any known coating technique, including for example spraying, immersing, roll coating, or flow coating. Moreover, hexavalent chromium compounds such as are used in some of these systems are classified as carcinogens by these agencies. conversion coatings, passivation of metals using aqueous solutions using aqueous acidic solutions with pH less than 6 not containing phosphates, hexavalent chromium compounds, fluorides or complex fluorides, molybdates, tungstates, vanadates or oxalates, Treatment of iron or alloys based thereon, Treatment of zinc or alloys based thereon, Chemical surface treatment of metallic material by reaction of the surface with a reactive liquid, leaving reaction products of surface material in the coating, e.g. TABLE 6 One well-known coating technique is reverse roll coating, in which a sheet of metal is pulled between counter-rotating cylinders, i.e. The method includes combining in aqueous solution a phosphonic acid, polyvinyl alcohol, and a catalyst selected from the group consisting of group IV-B compounds, boron compounds, vanadium compounds, and molybdenum compounds. It has been found that phosphonic acids comprising amine functionality, especially secondary or tertiary amine functionality, are often particularly effective, and such compounds include (but are not limited to) acids according to structures II and III above. Boiling phosphonic acid at levels exceeding the LOQ more frequently than products labelled as organic (39% vs. 17%) – see tables of the main findings in conventional and organic products. — Owner name: LOSS % SURFACE 23 mm The required pH may be obtained by adding ammonia, if needed, to raise pH to the desired level.

Average cured powder coating thickness was 1.5 mils. Known methods of treating metal surfaces to improve paint adhesion and corrosion resistance of the painted metal surfaces include two general classes of chemistries. 98.8 Also, in some embodiments, it is desirable to minimize the presence of alkaline earth metals, with the same typical limits applicable as noted above for alkali metals. The range of variation included the absence of phosphonic acids at one extreme and the absence of polyvinyl alcohols at the other. A-5 As the sheet metal is passed between the cylinders in a direction against the direction of rotation of the cylinders, some wiping force is applied to the metal. In a pretreatment coating operation, a coil (roll) of metal is unwound, cleaned, pretreated with the conversion coating to improve corrosion resistance and/or paint adhesion, and then decorated (e.g., painted and baked).

Thus, for example, a significant amount of the phosphonic acid component may actually be in the form of a salt (such as an ammonium salt) in the composition, but amounts of phosphonic acid are calculated based on the free acid itself. 165 — Panel Phosphonic acid and polyvinyl alcohol conversion coating. Without wishing to be bound by any particular theory or explanation, it appears that group IV-B elements, such as zirconium, increase the interaction between the composition and the metal surface, in effect helping to bond the composition to the metal surface. Chromium compounds have been used as traditional conversion coatings to treat metal surfaces. 3.0 Most phosphonates are highly water soluble, while the phosphonic acids are only sparingly soluble. %PDF-1.7 146,000-186,000 About the choice of the protogenic group in polymer electrolyte membranes: Ab initio modelling of sulfonic acid, phosphonic acid, and imidazole functionalized alkanes. Celvol ™ In inorganic chemistry, phosphonic acid is a phosphorus oxoacid with a formula of H3PO3, more commonly known as phosphorous acid. acid The compositions may be applied from an aqueous carrier to a metal surface and then dried to form a coating imparting good paint adhesion and corrosion resistance to the metal substrate. In some embodiments of the invention, R1 comprises a structure according to formula II For example, 0.352 to 3.52% nonvolatiles, such as may typically be used for storing and shipping the product.
