Abstract
The laboratory countertop of the present invention utilizes a thin chemical and heat resistant surfacing panel in the form of a thin planar sheet made of a cured thermoset resin composition. In accordance with one broad aspect of the present invention, the thin chemical and heat resistant surfacing panel is mounted overlying a backing panel of a less expensive and lighter material such as particle board or plywood. The surfacing panel is of a cast, monolithic construction and has a width at least 50 times its thickness and a length at least 100 times its thickness. The surfacing panel can additionally include an edge flange integrally formed with the thin planar sheet. The edge flange hides the underlying backing panel from view and gives the countertop the appearance of a unitary thick slab.
