    Abstract: An article comprising a dusty surface and a coating on the dusty surface comprising a coating polymer having a Tg less -20°C and a method of reducing dust are provided. In some embodiments, the coating polymer has a Tg less than -30°C, and in specific embodiments, the coating polymer has a Tg less than -45°C. The dusty surface may be, for example, crushed stone, coal, iron ore, gravel, sand or other aggregates (e.g. a roofing granule,) or a soil surface. Generally, the coating polymer comprises a polyacrylate, polyurethane, synthetic and natural rubber, silicone and other organic polymers. In specific embodiments, the coating polymer comprises an acrylic emulsion polymer.
