  • Publication number: 20040048954
    Abstract: The present invention is a pigmented coating composition, including a film-forming polymer comprising an epoxide polymer. The coating contains a mixture of crosslinking agents wherein at least one crosslinking agent is a polyamide functional compound and at least one crosslinking agent is a phenalkamine compound. The mixture of crosslinking agents is useful in stabilizing the pigment in the coating composition.

  • Patent number: 6656530
    Abstract: The refinish compositions contain an acetoacetate resin based on a monomeric polyol or a hydroxy-functional oligomer of such a polyol; a blocked polyamine (polyketimine and/or polyaldimine), pigment, and alkyd polymer. The alkyd is not reactive toward the acetoacetate resin or the blocked polyamine. The refinish compositions may be prepared from an intermix system that has a plurality of color bases and an unpigmented component. Each color base includes the alkyd resin and one or more pigments dispersed with the alkyd resin. The unpigmented component includes at least one of the acetoacetate-functional resin or the blocked polyamine. A drier for the alkyd resin may be included in one of the components or in a separate, additional component.

  • Patent number: 6436477
    Abstract: A polyurethane coating is prepared on a substrate using a multi-component coating composition having a first component containing a polyisocyanate material, a second component containing a polymeric polyol, and a third component containing a compound having at least two hindered secondary amine groups by first determining the temperature at curing of the coating will take place and then combining the first and second components and, when the cure temperature is less than about 20° C., particularly less than about 10° C., also combining the third component to prepare a combined coating composition; then applying the combined coating composition to the substrate and curing the applied coating layer.
