Abstract: The present invention is to a thermosetting epoxy functional (meth)acrylate resin which when formulated into a powder coating composition, applied and cured to form a powder coating on a metal substrate, provides excellent filiform corrosion resistance, without impairing powder coating clarity or wet adhesion.

Abstract: The present invention relates to a process for the manufacture of an epoxy-functional polyester, and to solid epoxy-functional polyesters made by such process and to a coating composition, in particular a powder coating composition, comprising such solid epoxy-functional polyester. The polyester made as disclosed herein is particularly useful in powder coatings.

Abstract: The present invention relates to a process for the manufacture of an epoxy-functional polyester. The process according to the invention comprises the steps of a) providing a polyester having functional groups selected from hydroxyl groups and carboxylic acid groups, or mixtures thereof, b) reacting the functional groups of the polyester with an epihaloalkane to obtain an epoxy-functional polyester dissolved in a liquid phase, c) optionally adding an organic solvent to the liquid phase obtained in step b); d) precipitating the epoxy-functional polyester from the liquid phase obtained in step b) or in step c); and e) isolating the precipitated epoxy-functional polyester from the liquid phase by a solid-liquid separation technique. The thus obtained resin is in particular useful for use in powder coatings.

Abstract: The invention pertains to a method for providing a metallicor concrete surface of a chemical installation with a coating, which comprises the steps of:—providing a two-pack coating composition wherein the first pack comprises an epoxy resin and the second pack comprises an amine curing agent for the epoxy resin, the coating composition further comprising an organoboron compound of the formula (I), wherein X is anorganic group having 1 to 24 carbon atoms and is linked to the boron atom via a carbon-boron bond, and wherein Y is an at least divalent organic group having 2 to 16 carbon atoms, combining the first pack and the second pack to form a coating composition,—applying the coating composition to the surface of a chemical installation to form a coating layer, and—allowing the coating layer to cure at a temperature in the range of ?10 to 50° C. A chemical installation provided with a lining of a cured coating composition as specified above, and a suitable coating composition, are also claimed.

Abstract: The invention pertains to a method for providing a metallic or concrete surface of a chemical installation with a coating, which comprises the steps of—providing a coating composition comprising epoxy-functional resin, and amine curing agent for the epoxy-functional resin, wherein the coating composition comprises an organic silicon-containing compound selected from the group of organosilanes and organosiloxanes, with the molar ratio between the silicon atoms of the organic silicon-containing compound and the epoxy-groups in the coating composition being in the range of 0.20-0.75:1.00, —applying the coating composition to a metallic or concrete surface of a chemical installation to form a coating layer, and—allowing the coating layer to cure at a temperature in the range of 0 to 50° C.

Abstract: The present invention relates to a curable coating composition, comprising: (a) a curable coating resin comprising thiol-reactive groups, (b) a thiolated norbornene curing agent for the curable coating resin, the thiolated norbornene curing agent comprising on average at least 1.0 thiol group per molecule, and (c) an accelerator for accelerating the reaction between the thiol reactive-groups on the curable coating resin and the thiol groups on the thiolated norbornene curing agent. These coating compositions can be cured at ambient temperature and provide a coated surface that can be walked on after only a couple of hours. The coating compositions in general have a VOC below 250 g/L. The coating compositions can be used for the protection of large steel structures, such as ships, buildings, bridges, industrial plants, and oil production installations.
