Abstract:
Disclosed is a process for preparing a multilayered coated article that includes in sequence, a substrate (S), a surface treated silane based scratch-resistant layer (R), and a silane based topcoat layer (T). The scratch-resistant layer (R) is formed by applying a scratch-resistant coating composition onto the substrate, and at least partially curing the applied scratch-resistant coating composition. The scratch-resistant coating composition comprises a polycondensate prepared by a sol-gel process from at least one silane. The surface of the scratch-resistant layer is treated by flame, corona and/or plasma treatment. The topcoat layer is formed by applying a topcoat coating composition to the surface-treated scratch-resistant layer, and curing the applied topcoat coating composition.
Abstract:
A method and an assembly is disclosed for coating a web (1) of paper or board by a dry treatment agent, the method comprising the step of applying the treatment agent to at least one side of the moving web (1). In the method is used a treatment agent contains a binder capable of undergoing a change of state at least under the effect of elevated temperature. The web (1) after being treated with the treatment agent is subjected to at least an elevated temperature at which the binder becomes deformable, and the web is subjected to a lower temperature serving to set the binder so that the same bonds the treatment agent to the web surface. The solids content of the treatment agent is not less than 75%, preferably not less than 90%, whereby a drying step after the treatment is not required.
Abstract:
A corrosion-resistant coated strap is formed from an elongated metal strap base element having a width and a thickness and defining first and second sides and a pair of edge regions. A coating is applied and cured onto the base element. The coating has a substantially consistent thickness at the first and second sides and at about the edge regions. A method for making the coated strap includes providing a metal strap and conveying the strap through a coating apparatus. A powder is electrostatically applied on the first side of the strap, which covers the first side and the opposing edges. The powder is applied on the second side of the strap, covering the second side and the opposing edges. The powder is melted to form a flowable material and is cured on the strap. The coating method is carried out in an in-line strap manufacturing process.
Abstract:
A process for modifying the surface of a substrate containing a polymeric material by contacting the surface with the modifying agent to bond the modifying agent to the surface the process comprising providing a solution of the modifying agent in a solvent and subjecting the solution of the modifying agent to a zone of elevated temperature to vaporize the solvent and provide diffuse contact between the modifying agent and the surface of the substrate.
Abstract:
A process for the high-speed rotary application of a liquid coating agent containing at least one pigment and/or at least one extender onto a substrate, wherein the process comprises the steps: (a) directly supplying at least two liquid components in a specified quantity ratio which determines the qualitative and quantitative composition of the coating agent to at least one high-speed rotary atomizer or preparation of a premix from at least two liquid components in a specified quantity ratio which determines the qualitative and quantitative composition of the coating agent and supply of the premix to at least one high-speed rotary atomizer, (b) high-speed rotary atomizing the components directly supplied in step (a) or of the premix supplied in step (a) to the at least one high-speed rotary atomizer and (c) applying the material atomized in step (b) onto a substrate, wherein at least one of the components used in step (a) contains at least one pigment and/or at least one extender.
Abstract:
A method and system for coating a glass contacting surface with a thermal barrier and lubricious coating. The system uses a novel exterior surface mixing tip device wherein oxygen is supplied through a predetermined portion of one supply line, and a predetermined gas is supplied through a predetermined portion of another supply line enveloping the first predetermined portion.
Abstract:
The invention provides a manufacturing method of an optical waveguide able to precisely manufacture the optical waveguide having a waveguide construction as designed, and improve yield as one example. In this manufacturing method, a hydrolysis reaction of raw material gas of glass is caused within an oxygen-hydrogen flame by flowing the raw material gas, oxygen gas and hydrogen gas from a burner, and an optical waveguide forming area is formed by depositing glass particulates on a substrate. The oxygen-hydrogen flame is injected toward the optical waveguide forming area in a slanting direction on the substrate. An exhaust pipe is arranged on the discharging side of an injecting flow. Surplus glass particulates unattached to the optical waveguide forming area are sucked and exhausted by the exhaust pipe. The surplus glass particulates are sucked and exhausted by the exhaust pipe by inclining a suction port side of the exhaust pipe by an angle within a range from 5null to 30null with respect to a face of the substrate.
Abstract:
Provided is a ceramic coated product and a coating for it, making it possible to improve corrosion resistance, wear resistance and the like of a material to be treated, and heighten aesthetically commercial value by a thin film forming or producing method using low-priced equipment. An ejection powder and a reactive ejecting gas are ejected onto a surface of a material to be treated comprising a metal product, a ceramic, or a mixture thereof. The ejection powder is heated on the surface of the material to be treated and then is reacted with the reactive ejecting gas. The resultant product is activation-adsorbed onto the surface of the material to be treated and caused to diffuse and penetrate thereinto. Thus, a layer made of a nitride or other compounds is formed.
Abstract:
A magnetic recording disk having on its surface a texture structure of fine surface irregularities with reduced variations, which is suitable for high-density magnetic recording, and a method of manufacturing such a magnetic recording disk are provided. A magnetic recording disk has a substrate 11, 12 (16) coated on a surface thereof with a magnetic layer 13, a carbon layer 14, and a lubricating film 15. The substrate has on a surface thereof a texture structure of fine surface irregularities for reducing friction when the substrate is brought into contact with a head and controlling an amount of lift of the head. The fine surface irregularities have a height of 20 nm or less and are formed from a pattern shape or profile of a shield with a high-speed atomic beam emitted from a high-speed atomic beam source.
