Abstract:
The device for varnishing metallic elements (1) comprises support means of the metallic elements (1) to be varnished through powdered varnish and dispensing means of the powdered varnish through a screen printing plate (5), foreseeing rotation means (6) of the screen printing plate about a rotation axis and translation means (7) of the rotation means (6) to give said screen printing plate (5) a roto-translation motion with respect to the metallic elements (1) to be varnished. The process for varnishing metallic elements through powdered varnish consists of keeping each metallic element in suspended position during the deposition on one or more of its faces of at least one layer of powdered varnish after having been made to pass through a screen printing plate.

Abstract:
A process for preparing a chrome substrate for application of a polymer coating, wherein the substrate preparation enhances adhesion and durability of the adhesion between the chrome substrate and the polymer coating, involves contacting the chrome substrate with an acid solution for a period of time sufficient to modify the surface of the chrome substrate. In certain embodiments, the acid treatment is an anodic treatment. In accordance with certain aspects of this invention, the acid treated chrome surface is further treated with a silane compound to enhance adhesion with a subsequently applied polymer coating composition.
Abstract:
A method of coating a substrate includes the steps of applying an electrocoat to the substrate, applying a powder primer onto the electrocoat, and then applying a topcoat onto the powder primer. The topcoat typically includes a powder basecoat and a clearcoat. The powder primer is applied to the electrocoat without first curing the electrocoat before application of the powder primer. The powder basecoat is applied to the powder primer without first curing the powder primer before application of the powder basecoat. The clearcoat is applied over the powder basecoat after which the electrocoat, the powder primer, the powder basecoat, and the clearcoat are simultaneously cured in an oven.
Abstract:
In one aspect, a method of nanolithography is provided using a driving force to control the movement of a deposition compound from a scanning probe microscope tip to a substrate. Another aspect of the invention provides a tip for use in nanolithography having an internal cavity and an aperture restricting movement of a deposition compound from the tip to the substrate. The rate and extent of movement of the deposition compound through the aperture is controlled by a driving force.
Abstract:
The present invention concerns a method for preparing an organic copolymer film on electrically conductive or semi-conductive surfaces in two steps. The first step includes electrolysis of an electrolytic solution containing an adhesion primer, in contact with a surface. The second step corresponds to the reaction, at the surface obtained previously, of a solution containing the following species: a protic solvent, and a “radically polymerizable” monomer. The polymerizable monomer is solubilized in micellar form. The surfaces obtained with the use of this method, and their applications apply to preparation of microelectronic components, biomedical devices or screening kits, as well as kits for preparing an organic copolymer film on an electrically conductive or semi-conductive surface.
Abstract:
A film is formed on a planar surface by applying a granular layer on the planar surface by using electrostatic forces, and then finishing the granular layer to form the film. A converting line may be rebuilt to have devices employing this method. A multilayer sheet-like product comprising a film layer may be produced.
Abstract:
Processes for forming a coating on electroconductive flat blanks having two major surfaces and sheared edges are provided. Also provided is a process for forming a multi-composite coating on a pre-sheared, electroconductive, flat blank having two major surfaces and sheared edges. Methods for forming and coating metal blanks are also provided. The present invention further provides a pre-sheared, flat electroconductive blank having two major surfaces and coated with a multi-layer composite coating composition on one major surface. The present invention also provides a method for coating a continuous metal strip, optionally, thereafter forming a coated blank therefrom, and, optionally, applying a second coating to the blank.
Abstract:
A fast method of creating nanostructures comprising the steps of forming one or more electrically-charged regions (5) of predetermined shape on a surface (1) of a first material, by contacting the regions with a stamp for transferring electric charge, and providing electrically charged nanoparticles (7) of a second material, and permitting the particles to flow in the vicinity of the regions, to be deposited on the regions.
