Abstract

1389380 Moulding article with a protective surface AAKRONITE DECORATIVES Ltd 24 May 1973 [25 May 1972] 24982/73 Heading B5A A method of moulding an article having an integral protective surface comprises the feeding, into a mould 5, of a mixture consisting of a plurality of chemically inactive spheroidal members 4 of not more than substantially 100 mesh size and a polyester or acrylic bonding resin 1 of lower specific gravity whereby the members 4 migrate to a lower surface of the mould to form a compact layer which is held by the resin when hardened. A substrate 6, e.g. a mixture of polyester resin and calcium carbonate, may be applied to the resin after it has partially gelled. The members may comprise glass, nylon or silicon beads; the article formed may comprise a bench top, panel or tile. The moulding material may be fed to a rotary tubular mould and the members are thereby centrifuged to the mould surface; during hardening the sheet, in tubular form, is laid flat for the final hardening stage.
