Abstract: A resin coating is formed on a metal surface using an aqueous autodepositing resin composition that contains oxidizing agent, acid, and carboxyl-functional and/or hydroxyl-functional water-dispersible or water-soluble resin and, optionally, metal ions; the resulting coating, while still in its uncured condition, is subject to post-treatment with an aqueous solution containing from 0.5 to 5.0 g/L of amine and from 10 to 100 g/L (solids) of water-soluble amino resin molecules that bear at least two alkoxymethylamino, methylolamino, and/or imino groups; and the coating is then dried and cured. This provides a highly anticorrosive coating on the metal, and contrary to an analogous process in which the post-treatment solution contains amino resin but not amine, the post-treatment solution remains stable and provides continuing high quality coating performance even after a considerable amount of metal surface per unit volume of post-treatment solution has been processed.

Abstract: A tri-laminate body panel stiffener includes two polymer layers with or without a backing. One of the layers is a compliant foam layer mounted against a substrate while the other layer is a rigid foam layer mounted against the compliant foam layer. In another aspect of the invention the laminate comprises a backing member having an expandable foam mounted thereto with two or more opposing edges of the laminate being of non-straight construction such as being wavy or saw tooth. A pattern of holes may be formed through the foam and backing layers.

Abstract: Concentrates containing (a) an hydroxylamine sulfate accelerator, and (b) zinc, nickel, manganese, and phosphate ions are formulated into aqueous coating solutions for treating metal surfaces, such as ferrous, zinc, and aluminum surfaces. In the process of using this solution, hydroxylamine ions become depleted or reduced in concentration in the applied solution. A replenishing solution is added for reusing the solution until the replenished coating solution reaches a sulfate level of no more than 14 g/l.

Abstract: A coating apparatus is disclosed for applying a coating material on one or more zones of a substrate material. In one embodiment, the coating applicators have fluid-wicking strips that apply the coatings directly to the substrate, while in another embodiment, the fluid-wicking strips indirectly apply the coatings to the substrate via feed rolls. Metering mechanisms supply predetermined amounts of coating material to the fluid-wicking strips. Each coating applicator has a housing with a recess for receiving one the fluid-wicking strips therein. One of the fluid-wicking strips Is mounted in each housing which has a plurality of transversely spaced passageways. Each passageway of each applicator housing is fluidly coupled to its own separate air actuated metering mechanism which dispenses coating material to the portion of the fluid-wicking strip adjacent thereto. A desired quantity of coating material is simultaneously delivered via the metering mechanisms to each of the applicator housings.

Abstract: Described is an NCO-group-containing polyurethane prepolymer madefrom polyisocanyates and polyols derived from natural oils. The invention is characterized in that the polyol is obtained by transesterification in the presence of basic lithium compounds. Together with a tertiary amine used to accelerate the moisture curing, the storage stability is thus increased considerably. Up to 4.0 mmol of the lithium compound is used per kilogram of polyol, and 0.1 to 2.0% by wt. of the amine, relative to the total weight of the composition, is used as the accelerator. The polyurethane prepolymer is suitable not only for the production of adhesives but also for the production of foamed materials, in particular those dispensed from throw-away pressure vessels.

The substrate may, for example, be a metal vehicle door. The thermosettable adhesive is comprised of at least one polyol such as a polyether polyol, at least one epoxy resin, and at least one polyisocyanate.
