This invention provides method of treating a surface of exterior wood outside of buildings to inhibit the uptake of moisture into the wood by spraying on the surface of the wood an aqueous formulation consisting of one or more film forming non-chloride, long-chain polymers. The aqueous formulation forms a clear micro-film. Preferably, the long-chain polymer is polyethylene-vinyl acetate, polyurethane, or a combination thereof, wherein the clear micro-film contains no detectable volatile organic compounds. A clear colorant is added to the aqueous formulation to verify treatment. The clear colored micro-film maintains moisture content in the wood at 16 percent or less, allows for continued visual inspection of the surface of the wood for termite damage, does not rub off, get diluted with water, or become damaged by workers and pets who come into contact with the clear colored microfilm.

A method for manufacturing an aircraft floor rail includes a step of manufacturing, separately, a first part of the floor rail, comprising at least a first flange, from a corrosion-resistant first material, and a second part of the floor rail, comprising at least a second flange, from a second material having a density that is different from, in particular lower than, that of the first material, and a step of assembling the first and second parts of the floor rail by crimping.

A process for coating a surface of a nonferrous metallic article with a bi-layer polymeric coating, said method comprising: 1) Subjecting the surface of a nonferrous metal article to a chemical washing; 2) Heating the article whose surface will be coated, to a temperature higher than the melting temperature of the selected polymer and lower than the ignition temperature thereof; 3) Apply the first coating layer, with a polymer size of particle of less than or equal to 20 mesh, keeping constant the substrate temperature; 4) Applying a second coating layer of plastic on the first coating layer, after the first layer has adhered to the substrate surface, where the second layer can be the same or different polymer, with a particle size equal to or less than 20 mesh; 5) Heating further the ensemble of substrate and bi-layer coating to a temperature higher than the selected at step 2, but lower than the ignition temperature of the coating and, 6) Cooling the thus coated substrate to room temperature. The product obtained offers a smooth, nonporous surface, high adhesion of the coating to the substrate and it is ensured the covering of all the surface exposed to the chemical treatment of the first stage, so that the resulting coated substrate is suitable for use in the food industry.

Methods of protecting a submerged surface include applying an adhesion-promoting layer onto a surface. An inner polymer layer is applied onto the adhesion-promoting layer. The inner polymer layer is impregnated with a biologically active chemical substance that inhibits biofouling-induced chemical, biological, and bio-proliferative damage. An outer polymer layer is applied onto the inner polymer layer. The outer polymer layer is impregnated with a biologically active chemical substance that inhibits biofouling-induced chemical, biological, and bio-proliferative damage and that repels biofouling organisms to prevent invasion of the inner polymer layer.
