Abstract:
Novel formulations of chemically bonded phosphate glass-ceramic sprayable coatings are disclosed. The disclosed coatings retain all the positive attributes of similar coatings disclosed in recent patents and a patent application on corrosion and fire protection, and in addition, provide superior surface characteristics, which include, superior surface toughness and smoothness, better abrasion and acid resistance, less erosion and longer durability. They are phosphate-bonded glass-ceramic coatings that are pore-free, and therefore, water cannot penetrate into these coatings. Unlike the previous inorganic oxide-based phosphate coatings, the glassy phase in these coatings provides a translucent and dense surface. Due to smoothness of these coatings, they are hydrophobic and easy to wash. The component pastes are smoother to pump, do not settle during storage and transport, and in addition, do not exhibit pozzalinic properties or do not harden during storage. These coatings can be used in place of polymer-based coatings for corrosion and fire protection, heat reflection, for marine coatings applications, and as decorative coatings. The coating material itself may be cast into solid-shapes, or used as an adhesive, and its whisker- and fiber-reinforced composites can be used as thermal resistant, inorganic and yet flexible products for many applications related to high temperature environments, corrosive conditions, and in place of products vulnerable to microbial and bacterial attacks.
Abstract:
The present invention pertains to a coating composition based on a specific epoxy-functional siloxane oligomer and an amine-functional polyorganosiloxane. The coating composition is suitable for use on substrates subjected to outdoor conditions, in particular conditions where a high durability, a high UV resistance, and good anti-corrosive properties are required.
Abstract:
An anticorrosion and/or antibiofouling coating for a substrate. The coating comprises a corrosion inhibitor and/or a microorganism incorporated within the coating. The coating a sol-gel derived coating that may be formed from one or more ormosil compounds.
Abstract:
Disclosed are a paint composition for preventing corrosion and improving long-term durability of iron structure; and a process for forming an aluminum oxide coating layer using the same. The process for forming an aluminum oxide coating layer of the present invention includes steps of (a) preparing a powder mixture consisting of 0.2 to 0.5 % by weight of zinc (Zn) powder, 0.3 to 1.0 % by weight of chromium (Cr) powder, 0.5 to 1 % by weight of nickel (Ni) powder, 0.06 to 0.15 % by weight of phosphorus (P) powder and the balance of aluminum (Al) powder; and (b) uniformly dispersing the powder mixture prepared above into adhesive resin and spraying the dispersed mixture on a surface of the iron structure to form a coating layer. The process for forming an aluminum oxide coating layer of the present invention is an economical process capable of being simply constructed even at normal temperature, and therefore may be effectively used for preventing corrosion and improving long-term durability of iron structure by uniformly forming an aluminum oxide coating layer having excellent physical properties such as adhesion strength to surfaces of iron structures, elongation, flexibility, etc.

Abstract:
An aqueous conversion coating composition for treating metal substrates such as aluminum, aluminum alloys, zinc, zinc alloys, magnesium, magnesium alloys and steel to provide a conversion coating thereon. The conversion coating composition comprises a) a source of aluminum ions; b) a fluoro compound; c) at least one pH adjuster; d) a source of Group VIB metal ions selected from the group consisting of tungstate ions and trivalent chromium ions; and e) optionally, a preservative. The conversion coating composition provides a corrosion resistant coating on the metal surface and improves the adhesion of subsequently applied layers.
Abstract:
Mittel zum Beschichten von Metalloberflächen auf Basis vernetzender Polyesterharze als organisches Bindemittel, das, bezogen auf seine Gesamtmasse, 4 bis 20 Gew.-% Aluminiumschuppen und nicht mehr als 0,1 Gew.-% Isocyanatgruppen-haltige Verbindungen enthält. Vorzugsweise enthält das Mittel als organisches Bindemittel mindestens ein hydroxyliertes Polyesterharz, vorzugsweise mit einer mittleren Molmasse im Bereich von 2000 bis 15000, sowie eine Vernetzungskomponente für das hxdroxylierte Polyesterharz und einen sauren Vernetzungskatalysator. Ein Verfahren zum Aufbringen des Mittels auf Metallbänder im Bandverfahren wird ebenfalls beansprucht. Die Schichtauflage wird im Bereich von 3 bis 30 μm je nach Verwendungszweck eingestellt, wozu eine zweifache Beschichtung vorteilhaft sein kann. Beispielsweise kann das Mittel als „Verzinkungsersatz" dienen.
