Application of a resin to a pool surface to provide a colored finish that is ultraviolet resistant. The resin may be a powder that can be melted at a fairly low temperature and applied to the pool surface. A first later of resin may be applied to an epoxy layer that is applied to the pool surface to provide better adhesion while the epoxy is still tacky (hot-flocking). The hot-flocking causes the resin and the epoxy to blend into a single layer. An additional layer of resin may be applied after the epoxy and the first layer of resin fully cured. After the second layer of resin has cured an additional layer may be applied to provide designs and/or markings. The designs/markings may be produced with tape and/or stencils and the next layer may be applied to the non-covered areas to provide the desired look.

A culinary item includes a hollow metal cup having a bottom and a sidewall extending up from the bottom, said cup having a concave interior face designed to accept food products and a convex exterior face, said interior face or said bottom being coated with a coating which consists successively, starting from the cup, in a hard sub layer and a sol-gel coating, wherein the hard sub layer takes the form of a discontinuous layer, in that the hard sublayer is porous and in that the hard sublayer is made up of one or more non-fluorinated polymer materials selected from polyetherary I ketones (PEAK) and mixtures thereof, possibly containing hard inorganic fillers, possibly conductive fillers and possibly less than 3 wt % of additives with respect to the weight of the hard sublayer.

The invention provides a powder coating composition comprising of thermoplastic polymers, ceramic particles, and cermet particles for lowering the friction coefficient, and improving wear and corrosion resistance of coated surfaces in high-temperature, high-pressure, and corrosive environments. It also provides a method of coating application for improving adhesion of the coating to the substrate. The coating compositions are devoid of volatile organic solvents and can be applied on surfaces using thermal spraying, compression molding and other particle sintering approaches. A multilayer architecture consisting of an adhesive bottom layer and a non-adhesive, low friction top layer is disclosed. The coating can be used in oil and gas production and seawater injection.

Application of a resin to a pool surface to provide a colored finish that is ultraviolet resistant. The resin may be a powder that can be melted at a fairly low temperature and applied to the pool surface. A first later of resin may be applied (thermally sprayed) to an epoxy layer that is applied to the pool surface after the epoxy has become tacky and before it has cured to provide better adhesion and cause the resin and the epoxy to blend into a single layer. An additional layer of resin may be applied after the epoxy and the first layer of resin fully cured. After the second layer of resin has cured an additional layer may be applied to provide designs and/or markings. The designs/markings may be produced with tape and/or stencils and the next layer may be applied to the non-covered areas to provide the desired look.

A method for applying a partial coating to a metallic substrate including providing a substrate to be coated, inserting the substrate into a reactive area of a thermal source, inserting precursor compounds into the reactive area of the thermal source to produce coating additives, and coating of the substrate through the coating additives produced within the reactive area of the thermal source.

The present invention discloses a method of preparing insulation coating. The method comprises: providing a powder of polymer material, a graphite powder, and a substrate, wherein the powder of the polymer material is an epoxy powder or a polyethylene (PE) powder. Next, forming a mixture via mixing the powder of polymer material and the graphite powder. Then, utilizing a thermal spray device to spray the mixture on the substrate and then cooling the substrate to form an insulation coating. The method possesses advantages of increased production efficiency and reduced cost, and provides an insulation coating with good sound insulation properties.
