Description

Originally a brand name for a series of Hardboard products made by the Masonite Company from wood fibers without the use of a urea formaldehyde adhesive. Tempered Duron® Hardboard contains wood fibers, paraffin wax, clay, titanium dioxide, calcium carbonate and talc. The rolled board is then dipped in oil and baked at 290-340F to increase its hardness and water-resistance. The tempering process also makes the board denser, stronger and darker. It is smooth on both sides. Tempered hardboard is typically used in construction siding. It is unsuitable for painting due to the oiled surface. The Masonite company no longer makes Duron.
