Abstract:
A system and method for depositing a coating may comprise a coating chemical reactor, surface activation component, and a deposition component. A target surface may be prepared for deposition with the surface activation component. The coating chemical reactor may comprise a coating chemical dispenser and a coating chemical verifier that prepares the coating chemical for deposition. The coating chemical verifier may utilize an optical excitation source and at least one optical detector, wherein chemical substances are identified by unique signatures composed of binary code. The coating chemical may be received by the deposition component to depositing the coating chemical on the target surface.
Abstract:
The invention relates to a method for functionalising a surface of a solid substrate with at least one acrylic acid polymer layer, said method comprising the steps of: i) placing said surface in contact with a solution consisting of at least one acrylic acid homopolymer, a solvent and, optionally, metal salts; ii) removing the solvent from the solution in contact with said surface; and iii) binding the polymer to said surface by thermal treatment.
Abstract:
Process for the treatment of shoe soles through ultraviolet radiation combined with ozone. The treatment is applicable to the surface of sole materials which are used in the shoe making industry in order to improve their adhesion properties with various adhesives. The treatment comprises applying low wave length ultraviolet radiation to the sole material by means of an apparatus having a chamber which contains ozone; introducing the sole inside the chamber; controlled removal of ozone, and a system for expelling the treated sole from the chamber.
Abstract:
The invention relates to a method for applying a primer, in particular a primer for UV coating systems, on an electrically conductive substrate, in particular a metal surface, comprising the steps of the treatment of the surface with process plasma providing an activated surface, and subsequently contacting of the plasma treated surface with a primer. The invention further relates to a pretreated surface comprising an electrically conductive substrate and a layer of a primer, which form an activated treatment surface for the treatment with a color characterized in that the activated surface is stable for at least several hours and a printed surface, in particular a printed surface comprising an electrically conductive substrate, a layer of a primer and a printed color layer, characterized in that the printed color layer is stable after immersion in water for more than 48 hours.
Abstract:
A method using irradiation with optical light in the presence of a chemical dissolved in a solvent, which chemical reacts with the surface in the presence of the irradiation to modify the surface (12A, 104A, 202A, 304A, 402A, 502A) of a substrate (12, 104, 202, 304, 402, 502) is described. The light can be pulsed or continuous. The method is significantly enhanced by the presence of water (14, 124, 204, 308, 410, 508) as the solvent containing the dissolved chemical on the surface. The treated surfaces are more paintable and bondable.

Abstract:
A method using irradiation with optical light having a wavelength of 160 to 500 nanometers without higher wavelength with coiling of the surface during the irradiation to modify the surface (12A, 104A, 202A, 304A, 402A, 502A) of a substrate (12, 104, 202, 304, 402, 502) is described. The light is filtered or the lamp (24, 106, 212, 306, 510) is restricted to the limited range to avoid the effects of the higher spectra. The light can be pulsed or continuous. The method is significantly enhanced by the presence of water (14, 124, 204, 306, 410, 508) on the surface, preferably also in the presence of ozone in the water. The treated surfaces are more paintable and bondable.
Abstract:
A process for improving surface properties of a material comprises irradiating the material with ultraviolet rays in vacuo or in an inert gas atmosphere to destroy atom-to-atom bonds of predetermined surface groups and remove specific atoms, and reacting the activated surface with radicals of a reactive gas or coating agent activated by irradiation with ultraviolet rays or laser beams to thereby produce new surface groups and modify the surface properties according to a particular purpose. An apparatus for conducting this process comprises a closed vessel (1) having an ultraviolet ray discharge tube (2) provided therein and an inert gas feed pipe (6), a reactive gas feed pipe (7) and a degassing apparatus (F) connected thereto to make the inside selectively vacuum or an atmosphere of inert gas or reactive gas.
