  • Patent number: 5082609
    Abstract: A panel having a finish face, a substrate and a lamina of moulded polyurethane between the two is formed in a single closable die having two portions, the first stage of the operation being to spray a release agent onto a face forming surface of one die portion, then spray an aliphatic polyurethane colored film onto the release agent, spray an elastomer polyurethane over that film and allow the elastomer to at least partially set, lay a sheet of reinforcing fibre which can for example be a continuous filament glass over the at least partially set elastomer, dispense the liquid ingredients of a rigid foam polyurethane over the glass, close to the mould, and remove the product after setting.
