  • Patent number: 6559204
    Abstract: An autodepositing liquid composition comprises dispersed non-film-forming polymer particles in addition to the dispersed film forming polymer characteristic of all autodepositing liquid compositions. Preferably, the non-film-forming polymer particles are gas-tight microballoons filled with a gas such as air and have an average particle size less than 1 &mgr;m. Such particles act in the autodepositing liquid compositions and in the dried coatings formed from them as opaque white pigments, unless the coatings are heated above about 130° C., if so heated, the coatings, unless they contain other heat stable pigment, become irreversibly transparent.

  • Patent number: 6554915
    Abstract: Fairly pure metallic nickel may be efficiently dissolved in non-oxidizing acid. If the nickel includes individual pieces longer than 0.5 mm in any linear dimension, oxidizing agent is preferably added from the beginning of dissolution, while if the nickel is powdered so that no single piece has a linear dimension longer than 0.35 mm, oxidizing agent is preferably added only after most of the originally supplied nickel has been dissolved. After oxidizing agent is added, most or all of the remaining undissolved nickeliferous solid will then dissolve. The temperature of the reaction mixture of acid liquid and solid nickel preferably is room temperature at the beginning of dissolution but is raised in steps to a final value of at least 65° C. and maintained at that temperature for several hours.

  • Patent number: 6518356
    Abstract: The invention relates to the addition of dyes to aerobically curable adhesive compositions based on free-radically polymerizable compounds. The dyes serve as user-friendly indicators for monitoring the oxygen intake required to trigger the polymerization. The indicator dyes are especially suitable for aerobically adhesive compositions which contain activator systems for forming peroxides upon contact with air. Suitable dyes and indicators are those whose color change in aqueous solution lies within a pH range from 3.0 to 6.5.

  • Patent number: 6505740
    Abstract: A package containing an organic solvent or solution and a carrier or applicator sheet is produced from a laminated sheet material having a polypropylene surface layer that is resistant to chemical interaction with the solvent or solution. The package is formed by heat sealing the edges together and providing a resealable closure member along the top end. In one embodiment, the bottom wall is attached to the respective side wall along a seal line extending diagonally from the side edge of the side wall to the bottom edge of the side wall. The carrier sheets and solvent/solution are suitable for cleaning hard surfaces prior to applying a paint or other surface coating or for providing a “highlighting” liquid that helps detect surface finish defects and/or a temporary protective coating to prevent adhesion of weld splatter.

  • Patent number: 6478885
    Abstract: When a phosphate ester or a dispersed wax is added to a conventional liquid phosphate conversion coating composition, the resulting phosphate coating formed on a metal substrate has a lower coefficient of friction after being oiled than it would have had if the additive had been omitted. The corrosion resistance and paint adhesion properties expected from the conversion coating are not substantially diminished by the additive. Particularly good results are achieved if the phosphate coating composition contains calcium and ferrous cations and the liquid phosphate conversion coating composition is dried into place on the substrate.

  • Patent number: 6479103
    Abstract: Conductive and weldable anti-corrosive compositions based on (blocked) polyurethane resins, epoxy resins, together with curing agents containing nitrogen and conductive extenders are suitable for coating metal surfaces, in particular sheet steel in the coil coating process. These compositions are distinguished by a low stoving temperature, a distinct reduction in white rust on galvanized sheet steel in the salt spray test and by an improvement in the adhesion of the organic coating on the metallic substrate. These coatings furthermore also achieve adequate corrosion protection with a thin chromium coating, preferably also in Cr-free pretreatment processes. Sheet metal coated in this manner may be spot welded using any conventional processes.

  • Patent number: 6478860
    Abstract: A highly effective and storage stable conditioning treatment for metal surfaces prior to phosphating them is a suspension in water containing solid miorosize particles of at least one phosphate of a divalent or trivalent metal and an accelerant selected from the group consisting of sacoharides and their derivatives thereof, orthophosphoric acid, condensed phosphoric acids, organophosphonic acids, and polymers of vinyl acetate and/or carboxylic acid. The surface conditioning liquid composition is used simply by effecting contact between the metal and the liquid composition, and can also be used to simultaneously carry out degreasing, particularly when the conditioning liquid also contains nonionic or anionic surfactant.
