A method of forming a self-sealing fuel tank includes: providing a container including internal surfaces and external surfaces and configured to hold a fuel; forming a latex coating layer over at least a portion of the internal surfaces and/or external surfaces; depositing or encapsulating an environmental layer over at least a portion of the latex coating layer; where the latex coating layer swells when contacted with the fuel; and where the latex coating layer is formed from a latex coating composition that is substantially free of a non-ionic associative thickener.

A hydrogenated NBR composition comprising 30 to 200 parts by weight of titanium oxide and 1 to 8 parts by weight of magnesium oxide, based on 100 parts by weight of hydrogenated NBR. By forming a crosslinked rubber layer of the rubber composition on a metal plate, a gasket material with excellent blister resistance, whose roll kneadability is improved without reducing the rubber strength of hydrogenated NBR, is provided. Moreover, the rubber composition is effective as a rubber raw material for use in soft metal or a high hardness hydrogenated NBR material for which kneading processing is difficult.

A metal gasket material plate includes a sealing layer formed by layering a chemical coating layer, an adhesive layer, and a rubber coating layer in this order on at least one side of a metal plate. The chemical coating layer is formed by a thermosetting surface preparation agent including inorganic compound particles and a metal alkoxide compound. The adhesive layer is formed by an adhesive including an epoxy compound and an anti-corrosive pigment. The rubber coating layer is formed by a rubber agent including rubber.

A method for producing an intermediate material for a cooking device according to an embodiment of the present invention comprises the steps of: repeating a cycle of applying a dispersion of a fluororesin and an inorganic filler or a dispersion of a fluororesin alone to a supporter and firing the applied dispersion so as to form a multilayered fluororesin film, followed by exfoliating the multilayered fluororesin film from the supporter to acquire the multilayered fluororesin film beforehand; providing the pre-acquired fluororesin film on a metal-substrate; and thermally compressing the fluororesin film and the metal substrate. In addition, an organic compound-containing primer or adhesive is not used in the thermocompression step.

A method for making pots and pans, equipped with a multi-layer coating of non-stick material including the forming of multiple layers of coating of an inner surface of a wall delimiting a cooking cavity, performed by cyclical repetition of a step of applying suitable substances and subsequent drying and baking in an oven of said layers of substances applied, at least the final layer of said substances being obtained by using a non-stick substance. The method includes, before the step of applying the substance for forming at least the final layer coating the cooking cavity of the pot, a step of adding as an additive edible oil or grease to the liquid substance to be applied for forming said final layer.

Articles having poly(vinyl alcohol) (PVA) and silica nanoparticle multilayer coatings are provided. More specifically, the articles include a substrate and a multilayer coating attached to the substrate. The multilayer coating includes a silica layer that is the outermost layer, the silica layer containing acid-sintered interconnected silica nanoparticles arranged to form a continuous three-dimensional porous network. The multilayer coating also includes a PVA layer disposed between a surface of the substrate and the outermost silica layer. The PVA and silica nanoparticle coatings can be used on a large variety of substrates and tend to be resistant to impacts, scratches, wet abrasions, soil and fog.
