Windshields are difficult to recycle after use, especially the residue of fine glass (with small granulometry). This material is characterized as a residue since it cannot be recovered in the glass industry, because in the furnaces of glass fusion fine glass is avoided to prevent deposition on the internal walls of the furnaces and the drag of this fine powder through the chimney[1]. In this work two different granulometries of this fine glass - 200 mesh and 325 mesh - were used as a filler in a varnish based on a urethane-acrylate oligomer used to cover and protect wood flooring. The cure of this varnish was through ultraviolet radiation. The results showed increased abrasion resistance for the varnish with addition of the fine glass.
