The flip-flop properties and the metallic impression are enhanced in a metallic coating. The coating includes a colored base layer formed directly or indirectly on a surface of a coating target, and a bright material-containing layer containing flaked bright materials and a colorant and layered on the colored base layer. With respect to the bright material-containing layer in a state without the colorant, Y(10°) of the XYZ color system is set to be 50 or more and 850 or less, and Y(20°) is set to be equal to k×Y(10°), where k is in a range of 0.2≤k≤0.6 and is determined according to the Y(10°). The colorant concentration of the bright material-containing layer is determined according to k.
摘要:
A powder coating composition is provided herein. The powder coating composition includes a glycidyl-functionalized (meth)acrylic resin as a film-forming binder, a cross-linking agent (hardener) for the binder, particles chosen from the group comprising aluminum oxide Al2O3 and aluminum hydroxide Al(OH)3 particles, and a coating additive, the wt % based on the total weight of the powder coating composition. A process for the production of a scratch resistant powder coating is also provided herein. The process includes the steps of a) applying a transparent clear coat or a pigmented top coat directly onto a substrate surface or onto a prior coating, and b) curing the clear coat or the top coat applied in step a) wherein the transparent clear coat or the pigmented top coat includes the powder coating composition.

A process for preparing a container for a beverage, wherein the process includes applying a coating layer, which includes a food grade coating and an additive, such as monomeric resveratrol, to an inner layer of a container wall.
摘要:
The present disclosure relates to a method of preventing corrosion of mating surfaces of components. The method comprising impregnating a polyester based carrier with an anaerobic acrylic adhesive to form an impregnated carrier and spraying a pressure sensitive acrylic adhesive on one surface of the impregnated carrier to form an impregnated carrier having a pressure sensitive acrylic adhesive layer, which is protected using a protective silicon release liner to configure a pasting surface. The pasting surface is pasted on a first component, such that pasting layer is in contact with first component. A second component is abutted to first component with the impregnated carrier there between and force is applied on first and second components such that the anaerobic acrylic adhesive oozes out from the impregnated carrier and coats both mating surfaces in absence of oxygen to commence and complete curing of anaerobic acrylic adhesive on the mating surfaces of the first and the second components.
摘要:
The present invention relates to a container for a beverage having an inner coating layer containing resveratrol, a process for preparing such a container, the use of said container for the storage of a beverage and the use of resveratrol as an additive to coating layers of such containers.
摘要:
The present invention relates to a multilayer coating method for preventing erosion due to cavitation capable of enhancing adhesion with a coating layer, reducing waste of the material by a bonding method of a film prepared during top coating, and simplifying a process even while ensuring wear resistance and high stiffness of the material itself by surface-treating the material by a different method from the related art.
摘要:
A method and composition for coating surfaces, a corresponding coating and the use of objects coated according to said method. A cleaned, metallic surface is contacted with an aqueous composition that is a dispersion or suspension, and drying and/or baking the organic coating or optionally, drying the organic coating and coating with an equivalent or additional coating composition prior to a drying and/or baking. The aqueous composition has a pH of 4 to 11 and contains an anionic polyelectrolyte in a quantity of 0.01 to 5.0 wt. % relative to the total mass of the composition, which may have a solids content of from 2 to 40 wt. %. The solids have an average particle size from 10 to 1000 nm. A coating forms on the basis of an ionogenic gel which binds cations released from the metallic surface that originate from a pretreatment stage or from the contacting.
摘要:
A coated steel sheet comprises: a steel sheet; a primer coating film which is arranged on the steel sheet and comprises an anti-corrosive pigment and an aggregate composed of primary particles; and a top coating film which is arranged on the primer coating film. The anti-corrosive pigment comprises at least one compound selected from the group consisting of a bivalent tin salt, a trivalent vanadium salt, a tetravalent vanadium salt, a tetravalent molybdenum salt, an oxycarboxylic acid salt, an ascorbic acid, a phosphorous acid salt and a hypophosphorous acid salt.
摘要:
A method for electroless coating of a substrate by applying an activating coat of polyelectrolyte or salt with a first aqueous composition, rinsing of the activating coat such that the activating coat is not entirely removed The activated surface that has remained after rinsing is then contacted with an aqueous composition in the form of a solution, emulsion or suspension to form an organic secondary coat (precipitation coat), and drying. The activating coat contains at least one cationic polyelectrolyte or at least one cationic salt in solution in water. The aqueous composition which forms the secondary coat contains constituents which can be precipitated, deposited and/or salted out and which are anionically, zwitterionically, sterically or cationically stabilized. The dry film formed in the process, which is made of the activating coat and the secondary coat, has a thickness of at least 1 μm.
