ABSTRACT:
A molding process, resinous formulations for use in the process, and the resulting products are disclosed characterized in that the product comprises mainly a bulk or fill resinous body having a film or skin of a cross-linked polyester resin formed about the body. Even though the body has intricate curving surface contours, the film is smooth and free of surface tears and blemishes. The product is molded by first spraying formulated, dry particles of a partially cured polyester resin against a hot mold to cause the particles to fuse and flow and form a substantially continuous skin or film on the mold. Thereafter, the bulk resin is added and the mold is heated to cure the polyester resin as well as the bulk resin and to interreact the bulk and polyester resins together to mold the bulk resin with a film of the polyester resin.
