The present invention relates to an acidic, aqueous, particulate composition having a high stability with respect to agglomeration for autophoretic deposition of organic-inorganic hybrid layers on metal surfaces, comprising, in addition to iron(III) ions, fluoride ions and at least one dispersed organic binder (B), pigment-binder particles comprising a pigment portion and a binder portion (B), such that the binder (B) comprises a polymer of at least one monomer having acid groups and at least one polymerizable double bond. Likewise, the invention relates to the use of an aqueous dispersion comprising pigment-binder particles comprising a pigment portion and a binder portion (B) for the production of a self-depositing composition as well as a method for autophoretic deposition on metal surfaces.

Self-precipitating aqueous particulate composition comprising pigment binder particles

A metal sheet, inclusive of a metal strip, having a front side and a back side, both the front side and the back side comprising a first coating having an average thickness in the range from 0.5 to 10 &#x3bc;m, wherein the first coating of the front side contains particles, which release divalent or multivalent metal ions upon the action of an acid, in such an amount that a self-depositing coating agent forms, upon contact with the front side, a second coating thereon, whereas this is not the case for the first coating of the back side. The first coating of the front side can be overcoated with a self-depositing coating agent. Cut edges that do not have a first coating can be covered with the self-depositing coating agent. Correspondingly coated metal sheets, as well as a method for the manufacture thereof, are furthermore within the scope of the invention.

Multi coated metal substrate and method for the production thereof

The invention concerns the use of a composition or premix based on volatile corrosion inhibitors comprising, in order to limit to a maximum the release and/or degradation of the volatile corrosion inhibitors when the composition or premix is being formed, either an efficient amount of a structuring agent consisting of at least one solid or pasty substance whereof the melting point ranges from 40 to 110&deg; C. preferably from 50 to 90&deg; C., or a liquid substance capable of forming, mixed with a mineral filler, a solid or pasty combination. The invention also concerns a composition based on volatile corrosion inhibitors comprising a composition based on volatile corrosion inhibitors comprising an efficient amount which contains an efficient amount of a solid structuring agent. The invention further concerns polymer based articles having as constituent said composition or premix; said article are useful for protecting metal parts against corrosion.

Use of a composition or premix based on volatile corrosion inhibitors, composition or premix, articles comprising said composition and preparation method

The invention relates to a process for the phosphatization of metallic substrates comprising the use of a phosphatization bath having a pH from 1 to 5.5 and which comprises from about 0.3 to about 25 g/l of zinc ion, preferably from 0.5 to 10 g/l, from 5 to about 50 g/l of phosphate ion, preferably from 8 to 30 g/l, and from about 0.01 to about 10 g/l, preferably from 0.03 to 3 g/l of a trivalent cobalt complex.

Bath and process for the phosphatization of metallic substrates,

Concentrate for activating and refining bath employed in processes of zinc phosphatization, characterized by the fact that it is based on an aqueous dispersion containing from 2 to 20% by weight of Jernstedt salts, the concentration of titanium in the dispersion consequently being from 140 to 10,000 ppm of Ti, this dispersion in addition containing:

Concentrate for activating and defining bath and bath obtained from this

Process for the treatment of aluminum based substrates for the purpose of their anodic oxidation, comprising a surface treatment or chemical etching step using an acid bath comprising at least one fluorinated derivative of titanium and/or of zirconium and/or of silicium as well as at least one acid of the group comprising NO.sub.3 H, SO.sub.4 H.sub.2 and phosphoric acid.

Process for the treatment of aluminum based substrates for the purpose

Process for denaturating water-dilutable paints and solvent-based paints, wherein said paints are treated by washing with the assistance of an aqueous denaturation phase whose pH is from 4.5 to 7 and preferably from 5 to 6 and which contains an effective quantity of at least one denaturation agent consisting of an amine molecule of formula ##STR1## or of formula: ##STR2## in which the substituents R.sub.1 to R.sub.7, which may be identical or different, represent:

Process for denaturating water-dilutable paints and solvent-based paints
