  • Phosphating processes and products therefrom with improved mechanical formability
    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.

  • Conductive organic coatings
    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.

  • Modified polyurethane hotmelt adhesive
    Patent number: 6465104
    Abstract: Hotmelt polyurethane adhesive compositions which are solid at room temperature and capable of being cured by moisture are obtained by combining the reaction product of a polyisocyanate and a low molecular weight polymer derived from ethylenically unsaturated monomers and containing active hydrogen groups such as hydroxyl with an isocyanate-containing polyurethane prepolymer derived from one or more polyols. The low molecular weight polymer component may, for example, be obtained by free radical polymerization of mixtures of unsaturated monocarboxylic acids, alkyl esters of unsaturated monocarboxylic acids, and/or hydroxyalkyl esters of unsaturated monocarboxylic acids.

  • Method for controlling the coating weight for strip-phosphating
    Patent number: 6461450
    Abstract: A process for controlling the layer weight during the phosphating of steel strip zinc-coated on one or both sides, using a phosphating solution which contains 1 to 6 g/l zinc ions and 10 to 30 g/l phosphate ions, characterized in that a Fe(II) ion content within the range of 3 to 100 mg/l is established in the phosphating solution. The higher the Fe(II) content, the lower is the layer weight. An alteration in the Fe(II) content of 3 to 20 mg/l results in an alteration in the layer weight of about 0.1 g/m2.
