Abstract:
This invention describes a metallic article coated with a radiation curable coating that exhibits resistance to weathering and UV exposure. The radiation curable coating is comprised of greater than about 95% solids by weight and is either clear or pigmented.
Abstract:
The invention relates to a guide block and a method for embodying divisions on a slide plane (22) of a guide block blank (47). The divisions (25) are applied to the guide block blank (47), then a base surface (26) for the slide plane (22) on the guide block blank (47) is pre-prepared. After introduction of a material (41) for application to the base surface (26), a local fusion of the introduced material (41) is carried out, by means of a non-contact heat input (35). Particular forms for the divisions (25) are generated by means of moving the guide block blank (47) and/or a beam (35) of the heat input (34) relative to each other. Finally the support surfaces of the molten material (41) are levelled to generate a planar support surface for the slide plane (22).
Abstract:
The present invention relates to a process for the production of metal substrates containing a protective coating, especially substrates based on iron, like steel, galvanized steel, or electrogalvanized steel, generally used in construction and in the automotive industry.
Abstract:
One embodiment of the present invention is a method for fabricating a low-k dielectric film that included steps of: (a) chemical vapor depositing a lower-k dielectric film; and (b) e-beam treating the lower-k dielectric film.
Abstract:
The invention is directed to the use of medium to high power (greater than or equal to 1 kW) and medium to high energy (greater than or equal to 1 MeV) electron beam or X-ray to cure coatings in thick complex three dimensional automotive bodies. The medium to high power, medium to high energy has sufficient throughput and penetration to permit curing through multiple layers of steel and, therefore, is able to penetrate shadows caused by the bends, folds and curves in automotive bodies. In addition, the medium to high power, medium to high energy beam has sufficient throughput and penetration to cure the thicker coatings that accumulate in surface cracks and crevices. The invention permits the use of electron beam curable coatings and, thereby, reduces the fire hazard, hazardous air pollutant, and volatile organic problems associated with the non-reactive solvents used in the solvent based paints conventionally employed in the automotive industry.

Abstract:
A plasma is produced in a treatment space by diffusing a plasma gas at atmospheric pressure and subjecting it to an electric field created by two metallic electrodes separated by a dielectric material, a precursor material is mixed with the plasma, and a substrate film or web is coated by vapor deposition of the vaporized substance at atmospheric pressure in the plasma field. The deposited precursor is cured by electron-beam, infrared-light, visible-light, or ultraviolet-light radiation, as most appropriate for the particular material being-deposited. Plasma pre-treatment and post-treatment steps are used to enhance the properties of the resulting coated products. Similar results are obtained by atomizing and spraying the liquid precursor in the plasma field.

One embodiment of the present invention is a method for treating silicon nitride (SixNy) films that includes electron beam treating the silicon nitride film.
Abstract:
A method for depositing a low dielectric constant film is provided by reacting a gas mixture including one or more linear, oxygen-free organosilicon compounds, one or more oxygen-free hydrocarbon compounds comprising one ring and one or two carbon-carbon double bonds in the ring, and one or more oxidizing gases. Optionally, the low dielectric constant film is post-treated after it is deposited. In one aspect, the post treatment is an electron beam treatment.
Abstract:
The invention relates to a surface-modified layer systems, a method for the production and use thereof. The invention in particular relates to surface-modified layer systems, comprising a substrate and a mono-layer at least partially arranged on said substrate. Said mono-layer is cross-linked in the lateral direction and covalently bonded by anchor groups to at least one surface of said substrate. Said mono-layer is also composed of low molecular weight aromatic and/or heteroaromatic compounds. The mono-layer which is cross-linked in the lateral direction is composed of low molecular weight aromatic and/or heteroaromatic compounds and is integral with the surface-modified layer system, and exhibiting the characteristics of a cross-linked solid. Said mono-layer protects the surfaces of the corresponding substrate from damage caused by friction and corrosion in a particularly advantageous manner.
