Abstract: The present invention provides a polyurethane coating composition comprising a fluorosurfactant, a silane adhesion promoter, and a silane modified polyisocyanate, wherein the composition has excellent substrate wet-out and adhesion under direct wet-on-hot and cold spray applications. The coating composition is particularly well suited to use with polyurethane pultrusion composites.

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.
