  • PROPPANT SAND COATING FOR DUST REDUCTION
    Publication number: 20180142140
    Abstract: The present invention provides for coating proppants, such as sand, with a resin-containing dispersion which dramatically reduces the dust generated during handling, for example in hydraulic fracturing, by protecting the surface of the particle from abrasion and degradation. Such resin-containing dispersion coated-sand may also reduce the wear on metal parts used in transporting such proppants.
