MC-30 dust oil is an asphalt-based dust oil that uses a penetrant to allow asphalt to bind with stone and dust. After proper curing, a coat of MC-30 does an excellent job of not only controlling dust but also holding existing stone in place. After several treatments of MC-30, a layer of asphalt may develop, which would make additional oil unnecessary. Emulsion prime coat is similar to MC-30 in that it uses asphalt to bind stone and dust. However, in place of the penetrant, this product uses water. The use of water makes emulsion prime coat a less expensive alternative to MC-30, albeit with limited durability.
