ABSTRACT:
Molded composites, useful for manufacturing for example entry way doors, furniture components, building decorative or structural components, etc., are produced by a process in which a substrate and surface finishing film are placed in a mold, the mold is closed, and reactive polymeric precursors are injected between the substrate and the surface finishing film. The injection pressure and the autogenous pressure incident to the curing of the reactive polymeric precursors deform the surface finishing film into intimate contact with a surface of the mold cavity, and simultaneously the polymeric precursors chemically bond to the surface finishing film.
