摘要:
The invention relates to a method for producing polymer-coated metal foils, comprising the following steps: (a) a base layer (7) is applied to a carrier foil (3) by means of a dispersion (5) containing particles that can be electroless-plated or electroplated in a matrix material; (b) the matrix material is at least partially dried and/or at least partially hardened; (c) a metal layer (19) is formed on the base layer (7) by subjecting the base layer (7) containing the particles that can be electroless-plated or electroplated to an electroless plating or electroplating process; (d) a polymer (23) is applied to the metal layer (19). The invention further relates to a use of the polymer-coated metal foil produced according to the invention for manufacturing printed circuit boards.

Lors d'un procédé pour apprêter une pièce (10) à peindre en matière à plastique, on revêt une surface (14) de la pièce d'une couche d'un apprêt (16). Puis, on revêt la couche d'apprêt (16) d'une couche d'une laque de révélation de défauts (18) et on inspecte la couche de laque (18) pour y détecter d'éventuels défauts. Par exemple, la laque est une laque polyuréthane. Dans le cas où l'on ne détecte pas d'éventuels défauts, on revêt la couche de laque (18) de révélation de défauts d'une couche de peinture (19) conférant à la pièce (10) son aspect final.

Coating solutions having anti-reflective and anti-static properties, a coating derived therefrom, a substrate (10) coated with the coating and methods for their preparation. A coating on the substrate (10) includes a hard coat layer (11), a conductive colloidal metal oxide material layer (12), and a sol-gel alkoxide polymeric material layer (13).

An emulsion type primer for powder coating, which is pollution-free and excellent in safety, achieves a good adhesion between a metallic material and a synthetic resin coating and contains water as a medium, and a process for producing a metallic material coated with a synthetic resin by using this primer. This primer comprises an acid-modified diene polymer, an organic amine or ammonia and water. A metallic material coated with a synthetic resin is produced by applying the primer composition onto the metallic surface, curing the same by baking and then coating it with the synthetic resin by the fluidized bed dip coating method or the electrostatic coating method.

Method for the continuous painting of moving elements, which is suitable advantageously, but not only, for the painting of elements of a rod-shaped type being fed along their longitudinal axis, such as strips for frames in particular, the method being especially suitable for the painting of elements having a variously shaped or moulded profile, the method including one or more applications of paint on the element (18) to be painted, a brushing step and a step of drying with ultraviolet rays, the paint being of a photosensitive type with a substantially 100% dry residue, the method comprising in sequence a first step of application of a first layer of paint on the element (18) to be painted, a step of removal, levelling and spreading of that first layer of paint on the surface of the element (18) to be painted and at least one second step of application of a second layer of paint, these three steps being followed by the step of drying with ultraviolet rays. Device for the continuous painting of moving elements, which is suitable advantageously, but not only, for the painting of elements of a rod-shaped type, such as strips for frames in particular, which are fed along their longitudinal axis, the device (10) being especially suitable for the painting of elements (18) having a variously shaped or moulded profile, the device (10) cooperating downstream with means for drying with ultraviolet rays and comprising means (11) for the continuous feeding of the elements (18) to be painted, the device (10) including a box-shaped structure (14) defining a substantially closed painting chamber, within which are contained at least two spraying assemblies (15-17), each spraying assembly (15-17) comprising a plurality of adjustably positionable spray guns (19) to deliver paint, the device (10) comprising at least one first spraying assembly (15), at least one first assembly (16) for the removal, levelling and spreading of the layer of paint and at least one second spraying assembly (17) arranged in sequence.
摘要:
A varnish impregnation method comprises passing fibrous sheet material through a first container (2) containing a low-viscosity liquid such as a solvent, and a second container (3) containing a varnish. The sheet material is passed between the two containers through a chamber containing an inert gas which is soluble in the low viscosity liquid.
