  • Patent number: 7875355
    Abstract: A multi-layer coating system comprising a hydroxyl-functional polyurethane dispersion is provided. The hydroxyl-functional polyurethane comprises the reaction product of a pre-polymer intermediate formed from the reaction of an isocyanate with an active hydrogen containing compound, such as a polyester polyol, with a compound having at least two amine groups and one hydroxyl group, such as a diamino alcohol. In addition, a waterborne basecoat composition is provided having improved rheology and pattern control. Such a waterborne basecoat composition comprises a hydroxyl-functional polyurethane dispersion an acrylic emulsion resin, a water-reducible polyester resin, and a cellulose ester.

  • Patent number: 7445373
    Abstract: Apparatus and method for mixing a fluid dispersion disposed in a container having either a cylindrical or a square shape. The apparatus includes a holding structure having a retaining structure connected to a base. The retaining structure prevents lateral movement of the container both when the container has a cylindrical shape and when the container has a generally square shape with a width substantially equal to the diameter of the cylindrical shape. The apparatus rotates the container about at least one axis.
