Duron

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. Tempered hardboard is typically used in construction siding. Viisually tempered hardboard is darker than untempered hardboard.
