LOW TEMPERATURE COATED PARTICLES FOR USE AS PROPPANTS OR IN GRAVEL PACKS, METHODS FOR MAKING AND USING THE SAME |
摘要 |
<p>Disclosed herein are free flowing coated particles and low temperature methods of making same. Each particle has a curable coating disposed upon a substrate. The substrate is a particulate substrate including an inorganic material, a particulate substrate including an organic material, a composite substantially homogeneous formed particle including a first portion of an at least partly cured binder and filler particles, or a hybrid particle having an inorganic particle as a core and a composite coating including at least partially cured resin and filler. The curable coating includes a continuous phase including resole resin and reactive powder particles embedded or adhered to the continuous phase. The reactive powder particles typically include resole resin, novolak resin, polyester, acrylic and/or urethane. A method including applying a coating including the continuous phase including resole resin and reactive or non-reactive powder particles embedded or adhered to the continuous phase.</p> |
