CURABLE RESINOUS COMPOSITIONS AND SCRATCH RESISTANT COUNTERTOPS DERIVED THEREFROM

摘要

A resinous curable composition comprises: (a) an epoxy resin; (b)at least carboxylic acid anhydride; (c) at least one inorganic filler, wherein at least 80% of the particles of the filler have a particle diameter size between about 10 to about 40 microns, and (d) at least one inorganic filler, wherein at least 80% of the particles of the filler have a particle diameter size greater than about 90 microns and is preferably either sand and/or granite chips. The curable composition may be hardened in the presence of a heat activated catalyst to render a scratch resistant hard surface, suitable for use as a countertop or laboratory bench top. The composition may contain as high as 89% inorganic filler.
