Further, the compositions may comprise (ii) one or more aqueous polymer, such as for use in coatings or non-cementitious mortars.

Tubulars are immersed in electroless nickel coating solution to coat the tubulars. Prior to the coating step the tubulars are blasted with a clean medium and washed and rinsed in alkaline solution. The tubulars are arranged in a bunk for washing, rinsing and coating. LLDPE stretch wrap applied to outer portions of the tubulars prevents coating of the outer portions. The tubulars are electrically separated from the bunk and the coating solution tank, and the tank is provided with anodic protection to prevent coating of the tank. The bunk is provided with a header assembly to provide solution flow through the tubulars via nozzles on the header assembly in addition to flow caused by the vortex effect created by velocity of fluid exiting the nozzles. The bunk is arranged in the solution tank so that the tubulars are at an angle to horizontal to efficiently remove hydrogen gas. Solution flow to the header assembly is filtered to remove particulates.

The present invention discloses single-walled carbon nanotubes horizontal arrays with ultra-high density and the preparation method. The method comprises the following steps: loading a catalyst on a single crystal growth substrate; after annealing, introducing hydrogen into a chemical vapor deposition system to conduct a reduction reaction of the catalyst; and maintaining the introduction of the hydrogen to conduct the orientated growth of a single-walled carbon nanotube. The density of the ultra-high density single-walled carbon nanotube horizontal array obtained by this method exceeds 130 tubes/micrometer, and an electrical performance test is performed on the prepared ultra-high density single-walled carbon nanotube horizontal array shows a high on-current density of 380 μA/μm, and the transconductance of 102.5 μS/μm.

To provide a process for producing a fluoroolefin copolymer powder for powder coating material, which presents excellent stability of a fluoroolefin copolymer solution obtainable by polymerization in its production process, and which is capable of forming a cured film having an excellent appearance when used for a powder coating material. A monomer mixture comprising specific monomers is polymerized in an organic solvent in the presence of specific amounts of hydrotalcite and at least one compound (B) selected from a potassium salt, a sodium salt, a magnesium salt and a hindered amine-type light stabilizer, to obtain a suspension; an insoluble component is removed from the suspension to obtain a fluoroolefin copolymer solution having a pH of from 3.8 to 6.5 and an APHA value within a range of from 1 to 200; and the organic solvent is removed from the solution to obtain the fluoroolefin copolymer powder.

An UV (ultraviolet), IR (infrared) and NIR (near infrared) protection system and method for surfaces or substrates that experience degradation from solar radiation, UV/IR/NIR exposure. The method for protecting a substrate from UV degradation includes treating a surface of the substrate to allow a UV blocking agent to adhere to the surface of the substrate, applying the UV blocking agent to the surface of the substrate, and allowing the surface of the substrate to harden, thereby adhering the UV blocking agent to the surface of the substrate. The UV/IR/NIR protection system is tunable so that specific ranges of the UV spectrum may be blocked to reduce or eliminate UV degradation. The UV protection system may be in the form of a dispersion, suspension, emulsion, or in other liquid application form; in a solid particle form; or a pre-mold/precast transfer medium when applied to or it becomes the given substrate.

A panel including a surface made of a synthetic material may be subjected to a material removal process to create a specific decorative or architectural appearance. In one embodiment, a panel of cellular PVC is blasted with an abrasive material such as crushed glass to create a realistic stucco appearance on the panel surface. Benefits related to using certain synthetic materials as cladding may be realized, such as weather resistance. A coating containing aggregate may be applied to the blasted panel to enhance the surface appearance.

A release agent for a hot-forging die, containing micronanobubbles.

Methods and systems of the invention, for achieving a liquid-applicable, aqueous-based coating composition that forms a water-impermeable, vapor permeable barrier coating when applied onto a construction surface and allowed to dry, involve mixing together separate first and second components, wherein the first component comprises an acrylic emulsion, flame retardant, clay, and optionally at least one additive selected from thickeners (e.g., cellulosic), fillers, and other conventional additives; and wherein the second component comprises a freezing point depressing agent with a specific type of thickener selected from the group of associative thickeners, alkali soluble emulsion thickeners, or mixture thereof, to obtain the liquid-applicable coating. The present invention achieves low temperature film formation without reliance upon calcium nitrite, calcium nitrate, or sodium chloride type of freezing point depressing salts. The coating can be applied at low (e.g., sub-freezing) temperatures onto a construction surface such as wood, fiberboard, gypsum, cement, concrete, and other building substrates to achieve an effective barrier membrane.
