Abstract: An aqueous dispersion along with methods for producing and uses for the same. Where the aqueous dispersion includes crosslinkable reactive silicone organic copolymers of ethylenically unsaturated monomers and of ethylenically functionalized silicone polymers and is obtainable by means of radically initiated miniemulsion polymerization in an aqueous medium.

Abstract: Proppant particles coated with a resin system containing a reactive resin and an organopolysiloxane having at least three successive siloxy units and at least one pendent or terminal group which contains at least four atoms selected from C, N, P, O, and S, exhibit higher degrees of coating and decreased fracture and release of fines at high pressure, thus enhancing fracking performance.

Abstract: Coated proppants useful in fracking operations in oil and gas production are coated with a novolac resin containing a linear or cyclic organopolysiloxane of specific composition. The coatings are more fracture resistant, thus producing less fines during use, resulting in longer production campaigns.

Abstract: Coated proppants for use in fracking operations for oil and gas production are coated with a reactive resin composition containing 80-99.5 wt. % of a reactive polymer resin, and 0.5 to 8 wt. % of an alkoxy-functional silicone resin. The cured coating exhibits high fracture resistance and yet the proppant particles are free flowing.

Abstract: Coated proppants which exhibit superior proppant coatings and less fines generation are prepared by coating proppant particles with a reactive hybrid resin prepared by reaction of a phenol-formaldehyde resin and a co-reactive organopolysiloxane having at least three repeating siloxy groups, and is in free flowing form.

Abstract: Proppants coated with a curable resin containing 2.5-12% of a hydrophobic fumed silica having a BET surface area of 20 to 600 m2/g exhibit high resistance to cracking and flaking, and are useful in fracking operations in subterranean formations for recovery of oil and/or gas.

Abstract: Organopolysiloxanes bearing regularly spaced pendent carboxylic acid groups or salts thereof have a block polymer structure and are derived by the double half-esterification of a dianhydride and a silanol- or carbinol-functional organopolysiloxane or sulfur analog thereof. The products can form stable aqueous dispersions without the need for a surfactant.

Abstract: Organopolysiloxanes having a greater degree of defined reactivity through epoxy, isocyanate, anhydride, amino, carboxy, and (meth)acrylate groups are prepared by cohydrolytic condensation of reactive group-containing precursors and other condensable precursors in amounts such that the reactive organopolysiloxanes product contains on average more than two reactive groups, less than 20% by weight of alkoxy groups, and a proportion of non-reactive optionally substituted hydrocarbon groups such that the ratio of non-reactive hydrocarbon groups to Si atoms is greater than 1.

Abstract: Aqueous emulsions of epoxy- and organo-substituted, branched organopolysiloxanes are prepared by emulsifying the latter in water with the aid of a dispersing agent. The emulsions are storage stable and are useful in multi-component coating, adhesive, and binder systems.

Abstract: A method of forming an article including a substrate and a cured film formed from a coil coating composition on the substrate is provided. The coil coating composition comprises a precursor to the coil coating composition and a matting agent comprising an amide-based polymer. The coil coating composition is applied to the substrate and cured to form a cured film having a first region having a first film thickness and a first gloss. The substrate is deformed to establish a second region of the cured film having a second film thickness that is less than the first film thickness and a second gloss. A coil coating system including the substrate and the cured film disposed on the substrate is also provided. The matting agent stabilizes gloss of the cured film, minimizing a difference between the first gloss and the second gloss of the cured film on a deformed substrate.
