A method for producing a coated proppant having an intermediate cross-linked terpolymer layer includes mixing a monomers solution including a first monomer, a second monomer that is different from the first monomer, a cross-linking agent, and an initiator. The proppant particle is combined with the monomers solution, and the monomer solution on the surface of the at least one proppant particle is polymerized to form at least one proppant particle having the intermediate cross-linked terpolymer layer on a surface of the at least one proppant particle. A resin solution including an epoxy resin, a curing agent, and graphene is mixed, and combined with the at least one proppant particle having the intermediate cross-linked terpolymer layer on a surface of the at least one proppant particle. The resin solution is cured to form the coated proppant comprising an intermediate cross-linked terpolymer layer.

This disclosure relates to a method for the in-situ encapsulation and/or insulation of piping using silicone-based compositions such as liquid silicone rubber materials and/or silicone foams. The method is useful for encapsulation and/or insulation of underground piping, particularly underground piping carrying high temperature (e.g., >120° C.) fluids, such as steam. The in-situ encapsulation and/or insulation may be done by inserting a hose into a pipe cavity so that a first end of the hose is remotely positioned next to the pipe and a second end of the hose is attached to a pumping system. A silicone composition is pumped through the hose and into the cavity surrounding from the remote first end of the tubing at a first predefined rate, and the hose is gradually withdrawn from the cavity at a second predefined rate. The silicone material is allowed to cure and become rigid, thereby encapsulating and/or insulating the pipe.
