The present invention relates to an apparatus () for curing radiation-curable coatings, which has at least one irradiation chamber () provided with a plurality of UV radiation sources (). It is provided according to the invention that a plurality of UV radiation sources () are arranged close to one another and interconnected to form one or more irradiation modules (), the illuminance inside a irradiation module () and/or between at least two irradiation modules () being spatially variable.

Apparatus for curing radiation-curable coatings

The present invention relates to a composition containing silico-organic nanohybrid and/or microhybrid capsules for scratch-resistant and/or abrasion-resistant coatings, wherein the silico-organic nanohybrid and/or microhybrid system includes one or more small metal oxide cores A and a substantially complete, silico-organic shell B, and the composition can be obtained by a reaction performed in situ, in a synthetic resin or in a synthetic-resin precursor compound, between metal oxide particles (KA-O) and at least one organofunctional silicon compound which contains an organofunctional group and at least one hydrolyzable group or at least one hydroxy group. The present invention also relates to the use of such compositions as the base for lacquers for producing a scratch-resistant and abrasion-resistant coating on a substrate as well as articles provided with corresponding scratch-resistant as well as abrasion-resistant coatings.

High-temperature resistant polymerizable metal oxide particles having a glass transition temperature of the homopolymerizable &gE;100&deg; C. and a core A. The core includes an oxide of a metal or semimetal of the third to sixth main group, of the first to eighth subgroup of the periodic table, or of the lanthanides, and has at least one group &mdash;(B) &mdash;X bound via the oxygen atom of the oxide or hydroxide, in which B represents a binding link, and X represents a reactive functional group, and w is equal to 0 or 1. The inventive particles are useful, in particular, for producing coating materials, molding materials and adhesives.

Organosilicon nano/microhybrid or microhybrid system composition for scratch and abrasion resistant coatings

The invention relates to a stratified material with a coating which is deposited on one side or both sides and which is comprised of a planar substrate containing acrylate. The synthetic resin is modified by means of high-temperature resistant, polymerizable nanoparticles having a glass transition temperature of the homopolymerizates &gE;150 &deg; C. Said nanoparticles comprise a core consisting of silicon dioxide and of at least one side chain which is covalently bound to the core via one or several oxygen atoms of the oxide, and which is of the formula (MeO) (Me&mdash;(CH ) &mdash;(OCO) &mdash;CR &boxH;CH ) , wherein Me represents Si or Al, x is 1 to 3, m is 0 and 1, n is 0 to 6, y is 1 to 3 and R represents H or CH , whereby the free valences of Me represent a binding to another oxygen atom of the core or are saturated by alkoxy radicals.

Stratified material and a method for producing the same

The invention discloses a support material for image-recording processes comprising a base material and a foam layer, wherein the foam layer consists a whipped, radiation cured foam containing tensides, still further an image-receiving material is disclosed which contains said support material in addition to a dye-receiving layer.

Polypropylene mixtures of increased stress-crack resistance and melt strength can be produced by irradiating polypropylene powders with low average particle diameters by low energy electron-beam accelerators with energies of 150 to 300 keV. The polypropylene mixtures produced are suitable particularly for producing films, sheets, panels, coatings, pipes, hollow objects and foamed materials.

Continuous method for producing polypropylene mixtures of increased

Method for the quality-controlled treatment of surfaces with a radiation-cured surface treatment, in which a finishing formulation is applied to the surface and is polymerically crosslinked under the effect of radiation. To enable the quality control to be conducted non-destructively and at reduced cost, it is proposed that the finishing formulation contains a proton-affinitive indicator substance analyzable by ion mobility spectroscopy and that the indicator substance escaping from the printed or coated surface after the radiation curing is analyzed by means of ion mobility spectroscopy.

Method for the quality-controlled finishing of a surface with a

The invention relates to a device to irradiate surfaces with electrons, especially to harden surface layers. The device includes a vacuum chamber that has an electron beam window; an electron beam-permeable film that closes off the vacuum chamber from the ambient medium; and an electron beam generating system, consisting of a cathode and a forming electrode which are connected to a high-voltage and beam current feed line. In order to achieve an increase of the electron beam power and to reduce the energy losses during the transfer out of the electron beam window in such a device, according to the invention, the forming electrode is designed as a tubular hollow body with inner hollow space lengthwise dividers and with a lengthwise slit that is open towards the electron beam window. A wire-shaped cathode is arranged in each hollow space segment divided off by the hollow space lengthwise divider.
