Description
A hard, mineral wax obtained from Lignite and Peat. Montan wax was first produced in northern Bohemia (Czech Republic). The brown coals of Oklahoma and Texas also contain as much as 13% montan wax. Though the crude product is dark brown, the wax, after purification with solvent extractions, is white. It contains esters of montanic acid (C27H55COOH). Montan wax has been used as a substitute for carnauba and Beeswax. It is used in shoe and furniture polishes, phonograph records, roofing paints, waterproof coatings, adhesive pastes, paper sizing, candles, carbon papers, and suncrack prevention in rubbers.
