A system for forming a coating on a substrate is provided. The system includes a first mix having a cement, a filler, a defoamer, a cement retarder, a dispersing agent, or any combination thereof. The system additionally includes a second mix having a fatty acid derivative, a synthetic resin, one or more organosilicon compounds, a pigment, a thickener, or any combination thereof. A coating composition is formed by mixing the first and second mix together. Lastly, the system includes a spraying apparatus that applies a wet film to the substrate wherein the cured coating does not yield to wet-rubs and does not stain (effloresce) with cold distilled water.

A cement composition is disclosed that includes a cement slurry and an epoxy resin system that includes at least one epoxy resin and a curing agent. The cement slurry has a density in a range of from 65 pcf to 180 pcf and includes a cement precursor material, silica sand, silica flour, a weighting agent, and manganese tetraoxide. The epoxy resin system includes at least one of 2,3-epoxypropyl o-tolyl ether, alkyl glycidyl ethers having from 12 to 14 carbon atoms, bisphenol-A-epichlorohydrin epoxy resin, or a compound having formula (I): (OC.sub.2H.sub.3)—CH.sub.2—O—R.sup.1—O—CH.sub.2—(C.sub.2H.sub.3O) where R.sup.1 is a linear or branched hydrocarbyl having from 4 to 24 carbon atoms; and a curing agent.

A mixture along with methods of preparing, uses and/or products made from the mixture and methods of preparing products made from the same. Where the mixture contains 0.5% to 10% by weight of one or more superabsorbent polymers and 90% to 99.5% by weight of one or more protective-colloid-stabilized polymers based on one or more ethylenically unsaturated monomers and optionally one or more additives. Where the percentages by weight are based on the dry weight of the mixture and wherein no mineral binder is present within the mixture.

Provided are compositions and methods of using a liquid suspension of hollow particles comprising a plurality of hollow particles, water, a suspending aid, and a stabilizer selected from the group consisting of a non-ionic surfactant, a latex, an oleaginous fluid, porous silica, and combinations thereof. The liquid suspension is homogenous. An example method includes statically storing the liquid suspension in a container for at least one week; wherein the liquid suspension maintains a difference in density from the top of the container to the bottom of the container of less than one pound per gallon while stored. The method further includes adding the liquid suspension to a treatment fluid; wherein the liquid suspension reduces the density of the treatment fluid; and introducing the treatment fluid into a wellbore penetrating a subterranean formation.
