    摘要： Provided is a fuel system comprising a fuel vessel, molded parts for a fuel and/or a tube for a fuel in which bodies are constituted from at least one of a thermoplastic resin and a synthetic rubber, wherein a coating layer is formed on the surfaces in at least one side of the insides and the outsides of the fuel vessel body, the molded part bodies for a fuel and/or the tube body for a fuel or at least one of connected parts in these bodies; the above coating layer is formed by curing a polyurethane resin composition comprising an active hydrogen-containing compound (A) and an organic polyisocyanate compound(B); and the above coating layer has a gasoline permeability coefficient of 2 g·mm/m 2 ·day or less at 23°C and a relative humidity of 60 % RH. The above coating layer is excellent in a permeation-preventing performance against an automobile fuel (gasoline barrier property), an adhesion property between fuel vessel body and molding parts or tube, a heat resistance and an impact resistance, a flexibility, a bending resistance, etc., then a fuel vessel, molded parts for a fuel and a tube for a fuel which have excellent performances are obtained.

    摘要： A two-part coating system comprises a first part comprising one or more aliphatic polyisocyanates, optionally blended with one or more "amine reactive" resins and/or non reactive resins, and a second part comprising one or more aromatic polyamines optionally blended with one or more oligomeric polyamines, such that the two parts, when mixed together and applied to the internal surfaces of pipelines, form a rapid setting impervious coating suitable for contact with drinking water.
