摘要:
A coated steel sheet includes a steel sheet, a galvanized layer disposed on both sides of the steel sheet, a chromium-free chemical conversion film disposed on the galvanized layers, an undercoat containing a color pigment disposed on one of the chemical conversion films, and an organic resin topcoat containing a brightening agent disposed on the undercoat, and the total thickness of the undercoat and the topcoat is 10 µm or less. The coated steel sheet is suitable for a television cover that has high brightness and a high capability of hiding the color and flaws of a substrate.

The invention relates to a method for producing coated spring-loaded steel rails especially for windshield wipers comprising a rubber or elastomer wiper blade. In said method, a cold-rolled steel rail blank is provided with a zinc layer, whereupon a zinc-containing anchor layer is produced, and a coating made of a polymerizable coating powder is applied to the anchor layer and is partially cured.
摘要:
A tough and long-lasting adhesion of polyolefins to metal substrates is realized by means of a process comprising the following four process steps, carried out in succession: a) mechanical cleaning of the metal surface; b) treatment of the metal surface with a water-alcohol solution containing at least an alkoxysilane and boric acid; c) thermal treatment of the surface coming from the (b) step; d) treatment of the so-treated surface with a poliolefin-based composition, containing zeolites and carbon black.

There are provided a method of manufacturing a reverse osmosis membrane and a reverse osmosis membrane manufactured thereby. The method includes forming a polysulfone layer by applying a solution including a mixed solvent containing two or more solvents having different solubility parameter values to a surface of a porous support; and forming an active layer on the polysulfone layer.
摘要:
Coating a metallic surface with at least one of a pretreatment composition prior to organic coating, with a passivation composition without intent for subsequent organic coating, with a pretreatment primer composition, with a primer composition, with a paint composition and with an electrocoating composition, wherein the coating composition includes particles on a base of at least one layered double hydroxide (LDH) phase characterized by the general formula [M2+(1±0.5)−x(M3+, M4+)x(OH)2±0.75]An−x/n.mH2O.
