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 polyolefin based composition, containing zeolites and carbon black.
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.

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:
A process for producing a repair coating on at least one metallic surface that is coated with at least one corrosion protecting coating A applied with at least one composition selected from the group of pretreatment compositions, of organic compositions and of silicon compound(s) containing compositions, whereby the at least one corrosion protecting coating A has been at least partially removed in the area Z, whereby a thin corrosion protecting coating B containing at least one silicon compound is applied with a solution or dispersion containing at least one silane, at least one silanol, at least one siloxane, at least one polysiloxane or any mixture of these (=“siloxane composition”) on at least a part of the area Z. Optionally, a further corrosion protecting coating C may be applied on the thin corrosion protecting coating B generated with the siloxane composition whereby the at least one further corrosion protecting coating C is generated with at least one organic composition like a primer, a wet-primer, an e-coat, a powder coat, a base-coat or a clear-coat or with at least one composition which is the same or another siloxane composition as for the thin film B.

摘要:
In a surface finishing method for a stainless steel material, excimer irradiation is made on a surface of the stainless steel material by emitting ultraviolet light to improve wetness. Then, a surface finishing is applied on the surface of the stainless steel material wherein the wetness is improved. In manufacturing a gasket, the stainless steel material or plate is cut in a predetermined shape, and holes and bead are formed in the metal formation plate. Then, the plate may be assembled with other plate.

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.

摘要:
A lighting sheet including an aluminum sheet with a substantially uniform, non-directional roll textured surface having an extended surface area (Ra roughness of about 15 to about 35 microinches) and a clear polymer layer not containing added particulate matter coated on the textured surface. The non-directional roll textured surface provides a uniform matte finish to the lighting sheet.
