The disclosure relates to a method for coating a substrate with particles, wherein the following method steps are carried out in a vacuum: positioning a substrate surface of the substrate to be coated in a vacuum and in the direction of a region in which there are disposed solid particles with which the substrate surface is to be coated; and; and introducing electrons into the solid particles for electrostatic charging of the solid particles in such a way that a force brought about by the electrostatic charging separates the solid particles from one another and accelerates them in the direction of the substrate surface of the substrate for coating of the substrate surface with at least a portion of the separated solid particles. A device that can be used in accordance with the disclosure has a particle container, a substrate holder and an electron source.

A method of manufacturing a core for a composite material sandwich panel, the method comprising the steps of: providing a sheet of balsawood with opposite major surfaces, with vessels and axial parenchyma cells of the balsawood extending between the opposite major surfaces in a thickness direction of the sheet; coating a layer of a curable resin composition onto respective opposite major surfaces of the sheet of balsawood; and curing the curable resin composition, wherein the resin composition is applied and cured so that the coating layer of cured resin composition unevenly fills or only partly fills outermost ends of at least some of the vessels in the balsawood and thereby provides, at least in the vicinity of at least some of the vessels, a non-planar outer surface of the coating layer of the cured resin composition over the opposite major surfaces.

Protective coatings and methods for forming them are disclosed wherein the coatings have increased abrasion, impact and scratch resistance as compared to known coatings. The coatings are made from environmentally friendly materials such as polylactic acid which can be derived from corn. The materials can be used to provide a protective coating on their substrate materials including especially wood for flooring and furniture. The coatings can have a hardness as measured on the Shore D Scale that can reach at least 75 to about 85 and enhanced resistance to abrasions, impact or scratches and can be used to coat flooring or furniture surfaces. The coatings can contain from about 1 to about 10 mass percent of triallyl isocyanurate with respect to polylactic acid.

The method according to the invention consists in that the carrier is covered with at least two varnished layers, the two layers being made of electron curable varnishes, which may contain an additive increasing adhesion between the layers, and if the layer which is applied first, counting from the side of the carrier, containing an interlayer adhesion increasing additive, is irradiated with an excimer lamp and then pre-polymerized by electron radiation or UV light, then after applying the second layer also containing an interlayer adhesion increasing additive, the combined layers are cured by electron radiation or UV light. On the other hand, if the layer applied first, counting from the carrier side, is only pre-polymerized by electron radiation or UV light, then after applying the second layer, which then contains an additive increasing adhesion between the layers, it is subjected to irradiation by an excimer lamp and then the combined layers are cured by electron radiation or UV light. As a result, it is possible to obtain a product whose layer refined with excimer lamp and the layer only cured with electron radiation or UV light, are bound together regardless of the order of their occurrence.

Disclosed herein are radiation curable coating compositions including a mixture of crosslinkable polymers or oligomers in combination with at least one hydrophobic unsaturated monomer and at least 20 wt. % of hydrophilic unsaturated monomers. The coating of various substrates, in particular plastic substrates, with these coating compositions results in significantly improved surface roughness without the formation of undesired film defects. The coating compositions can be overcoated with commonly known coating compositions to produce multilayer coatings having an improved adhesion, especially wet adhesion, and a high optical quality. Further disclosed herein are a method for forming a coating onto an object and a coated object prepared according to the method. Additionally disclosed herein is a method of using the radiation curable coating composition to improve the surface roughness of plastic substrates, in particular plastic substrates produced by additive manufacturing.

A system for additively manufacturing a composite part is disclosed. The system comprises a housing and a nozzle. The nozzle is supported by the housing. The nozzle comprises an outlet, sized to dispense a continuous flexible line. The continuous flexible line comprises a non-resin component and a photopolymer-resin component. The system also comprises a feed mechanism, supported within the housing. The feed mechanism is configured to push the continuous flexible line out of the outlet of the nozzle. The system further comprises a light source, supported by the housing. The light source is configured to deliver a light beam to the continuous flexible line after the continuous flexible line exits the outlet of the nozzle to at least partially cure the photopolymer-resin component of the continuous flexible line.

The invention relates to a lubricant coating for a medical container comprising a cross-linked lubricant composition comprising a mixture of non-reactive silicone with reactive silicone, characterized in that the reactive silicone comprises a mixture of vinyl-based silicone and acrylate-based silicone. The invention further relates to a lubricant composition usable as an intermediate product in the fabrication of a lubricant coating.
