摘要： A process for producing a sealed stitched skin structure including the steps of: (a) providing a stitched skin member; (b) providing an aqueous thermoplastic polyolefin dispersion sealant coating composition; (c) applying the aqueous thermoplastic polyolefin dispersion sealant coating composition from step (a) to at least a portion of the surface of at least one side of the skin member to form a wet film or coating of the thermoplastic polyolefin dispersion sealant coating composition on the surface of the skin member; (d) drying the wet coating from step (c) on the skin member surface; and (e) heating the dried skin member from step (d) at a temperature sufficient to form a film or coating of the aqueous thermoplastic polyolefin dispersion sealant coating composition on the stitches of the seam in the skin member; wherein the film or coating seals the stitches in the skin member; a sealed stitched skin structure made by the process above; and a polyurethane foamed article.
