Abstract:
Die Erfindung betrifft oberflächenmodifizierte Metalleffektpigmente, die bedeckt sind mit einer Metalloxidschicht, wobei an diese Schicht eine Silanschicht gebunden ist, welche wenigstens zwei voneinander verschiedene bifunktionelle Silane aufweist. Die Erfindung ist besonders geeignet für Metalleffektpigmente aus Aluminium, Titan, Zirkonium, Kupfer, Zink, Gold, Silber, Zinn, Stahl und Eisen, insbesondere Aluminiumpigmente. Darüber hinaus betrifft die Erfindung auch ein Verfahren zur Herstellung der oberflächenmodifizierten Metalleffektpigmente und deren Verwendung in wasserbasierten, lösungsmittelbasierten oder strahlenhärtenden Beschichtungszusammensetzungen.
Abstract:
The present invention deals with metallic pigment comprising a metallic substrate coated with a hybrid inorganic/organic layer, wherein the hybrid inorganic/organic layer comprises a network of an inorganic component and at least one organofunctional silane component having organic functionalities which have not been polymerised. Additionally, the present invention deals with a method of coating a metallic substrate comprising: combining the metallic substrate with a surfactant and an organofunctional silane and an inorganic component precursor to form a hydrophobic phase; combining the hydrophobic phase with a hydrophilic liquid to form an emulsion comprising said hydrophobic phase containing the metallic substrate, the organofunctional silane and the inorganic component precursor dispersed in a continuous hydrophilic phase; adding a catalyst to the emulsion; and forming a hybrid organic/inorganic layer from the organofunctional silane and said inorganic component precursor on the metallic substrate to produce a coated metallic substrate.

Abstract:
Manganese vanadium tantalum oxide that can be represented by the formula MnxVyTazOw, where 1 = x = 3, 0.001 = y = 3, 0.001 = z = 2, and w = 7, and alternately, x = 1.25 = x = 2.45, 0.1 = y = 2.39, 0.2 = z = 1.9, and w = 7, methods of producing MnxVyTazOw, a particle that includes MnxVyTazOw and/or a chalcogenide glass layer, and a method of producing the particle are described. The disclosed manganese vanadium tantalum oxide has superior near- infrared reflective properties. The disclosed methods of producing the manganese vanadium tantalum oxide provide products with superior phase purity, appearance and performance and take health and safety into consideration. The construction of the disclosed particle combines the reflective properties of the substrate with the near- infrared reflective properties of MnxVyTazOw, while the chalcogenide glass layer provides aesthetic appeal. The disclosed method of producing the particle involves physical vapor deposition of MnxVyTazOw and/or the chalcogenide glass layer.
