Abstract
Mouldings of thermosetting resin are laid up in a mould comprising a suitably formed sheet of thermoplastic material. Esp. claimed for moulding of phenolic or polyester resins, to make boat hulls, windsurfers, shower cubicles, baths, etc. to provide the moulding with an integral superficial skin of thermoplastic material. Thermoplastic mouldings can be produced more rapidly from a master mould than series of thermosetting mouldings, thus improving the efficiency of prodn. Thermoplastics surfaces on thermosetting mouldings are e.g. easier to paint, less receptive to marine fouling.
