摘要:
A method of forming a coating on a food or beverage container, which includes spraying a coating composition onto an interior surface of the food or beverage container, where the coating composition includes a latex copolymer and a metal drier or crosslinking agent. The latex copolymer is a reaction product of monomers that include (a) one or more styrene-mimicking monomers containing one or more cyclic groups and one or more ethylenically-unsaturated groups, at least a portion of such styrene-mimicking monomers being polycyclic monomers containing ring unsaturation, and (b) one or more other ethylenically-unsaturated monomers. Preferably, the coating composition is substantially free of each of BPA, PVC, other halogenated monomers, and optionally styrene. The method may also include curing the sprayed coating composition, thereby providing the coating on the interior surface of the food or beverage container.
摘要:
A method for applying a layer of a second color according to a predetermined pattern, on at least one face of a metal substrate, which is entirely painted with a first color comprising applying a primer according to a predetermined pattern onto at least one face of a metal substrate, applying thereto a UV curable powder coating comprising a second color that is different from the first color, removing excess of UV curable powder coating such that the UV curable powder coating remains only at a location on the metal substrate determined by the primer, activating IR and UV energy in order to cure the UV curable powder coating, and forming a metal substrate decorated with at least two colors according to the predetermined pattern on at least one face of the metal substrate, and a system for performing the same.
摘要:
A resin-coated seamless aluminum can (10) having polyester resin coatings (5, 7) on the inner and outer surfaces thereof, the polyester resin coatings (5, 7) being formed on the inner and outer surfaces of an aluminum can body (1) via non-chromium inorganic surface-treating films (3, 3), the polyester resin coatings (3, 7) being formed of a lowly crystalline polyester to which have been introduced a copolymer unit stemming from a dibasic acid and a copolymer unit stemming from a polybasic acid having a valence of 3 or more.
摘要:
Disclosed is a method for manufacturing a light-reflection aluminum door frame molding which comprises a multi-coating-applied aluminum material to thereby improve corrosion resistance and reduce costs. A method for manufacturing a light-reflection aluminum door frame molding includes cutting a metallic plate into a predetermined size, performing anodizing on the metallic plate to form an oxidized film on a surface thereof, performing opaque clear coating and transparent coating on the metallic plate to implement light reflection, and performing press molding on the metallic plate to provide the metallic plate in the shape of a door frame molding.
摘要:
A surface-treated metal material, comprising: a metal material, and a coating film disposed on the surface thereof, the coating film containing (A) an organic resin having a glass transition temperature of more than 35° C. and not more than 100° C., and (B) an organic resin having a glass transition temperature of more than 100° C. and not more than 250° C.; wherein the difference between the glass transition temperatures of the organic resins (A) and (B) is 50° C. or more. There are provided a surface-treated metal material having a coating film which contains no environmental load substance such as hexavalent chromium, and is particularly excellent in scratch resistance, press formability, and corrosion resistance after the shape processing thereof, and also a process for producing such a surface-treated metal material.
摘要:
Coated articles may comprise one or more coating layers, including water resistant coatings. A method comprises applying such coating layers by dip, spray or flow coating. The methods can make coated containers, preferably comprising polyethylene terephthalate, from coated preforms. In some methods, the aqueous solutions, dispersions, or emulsions are substantially or completely free of VOCs.
摘要:
A magnesium alloy material for forming which can yield a formed body with high formability without using a lubricating oil or a solid lubricant such as molybdenum disulfide, a magnesium alloy formed body which is obtained by forming the magnesium alloy material for forming, and a manufacturing method of the magnesium alloy formed body are provided. A magnesium alloy material for forming which exhibits a friction coefficient of 0.2 or below at a forming temperature of 350° C. or below is obtained by coating a surface of a magnesium alloy material with an organic resin such as a water-soluble urethane resin, a water-soluble polyester resin, a water-soluble acrylic resin or a water-soluble epoxy resin or a resin obtained by modifying any of these organic resins, or an organic resin formed of any of these resins which contains a silane coupling agent, a colloidal silica, a lubricant, a metal alkoxide or the like. Further, a magnesium alloy formed body such as an automobile part or a container is manufactured by forming a magnesium alloy material for forming.
