20100179077COATING COMPOSITION FOR PROPPANT AND THE METHOD OF MAKING THE SAME - A coated proppant comprising a proppant particulate substrate and a coating layer on the substrate. The coating layer is formed from a composition comprising a resin, a curing agent, an adhesion promoter, and a toughening agent.07-15-2010
20100197848AMPHIPHILIC BLOCK COPOLYMERS AND INORGANIC NANOFILLERS TO ENHANCE PERFORMANCE OF THERMOSETTING POLYMERS - Curable compositions, cured compositions, and methods of forming the same, including an epoxy resin, a curing agent, an amphiphilic toughening agent, and an inorganic nanofiller, wherein the toughening agent forms a second phase having at least one dimension being on the nanometer scale.08-05-2010
20110024129POWDER COATED PROPPANT AND METHOD OF MAKING THE SAME - A process for producing a proppant particulate substrate having a coating layer thereon including the step of blending a proppant particulate substrate with a powder coating composition at a temperature sufficient to cause the powder coating composition to coat the proppant particulate substrate with a powder coating; and a proppant particulate substrate coated by such a process.02-03-2011
20110058948WINDMILL PROPELLER BLADE AND METHOD OF MAKING SAME - A windmill blade which comprises reinforcing fibers in a toughened resin matrix. The resin matrix is made from a composition which comprises (a) one or more epoxy resins and/or one or more epoxy vinyl ester resins, (b) one or more reactive diluents, and (c) at least one amphiphilic block copolymer. The amphiphilic block copolymer comprises at least two different polyether blocks and is present in the composition in an amount of from about 0.5% to about 10% by volume, based on the total volume of the matrix composition.03-10-2011
