A MULTI-LAYER COMPOSITE STRUCTURE

摘要

The structure is formed of a substrate having bonded to it a finished layer on one side, and on the other side a layer of plastics (which may be reinforced) is chemically bonded to form a laminated structure. The plastics layer has a thickness and a density such as to provide the product with resistance to high impact and/or thermal shock. The finished layer is resilient to delamination when subjected to relatively high impact applied directly to the finished and/or plastics layer surface and to delamination when the composite structure is subjected to a sudden temperature change. The substrate may be steel and the finish layer on one or each side may be enamelling. The composite structure is suitable for a sanitaryware product such as a bathtub.
