Abstract: A moulding material composition for use in sanitary appliances, such as plastic sinks, baths, or wash basins, having a polyester resin in a monomer liquid having a polymerizable vinyl group, a thermoplastic non-shrink polymer, an organic peroxide, glass fibers, a stripping agent of either calcium or zinc stearate; and a filler material. The filler material can be either chemically coated glass micro-beads or calcium carbonate in a marble crystalline form. The calcium carbonate can be provided with or without a pigment coating. In particular, the pigment can be of a polyurethane epoxy material.

Abstract: A composite material facing that can be used in the building industry to achieve a wall facing cover including a high pressure polymerized polyester molded outer facing, and expanded polystyrene panel bonded behind the outer facing, a top edge back-set interlock having a groove which engages a tongue located in a lower edge of the adjacent facing, an invisible facing securing member extending through the insulating panel and located at a top edge of the facing in a back-set area concealed by a fitting of an adjacent facing, and the insulating panels for each facing being butted end-to-end without assembly. The interlock insures satisfactory flatness of the cover and reduces defects in the support.
