摘要： The present disclosure relates to a 2K coating composition comprising a polysiloxane-modified polyurethane and a hardener, wherein the polysiloxane-modified polyurethane obtainable by a method comprising the following steps: a) subjecting a polyol to a reaction with an isocyanate-functional silane coupling agent to obtain a silane-grafted polyol, and b) subjecting the silane-grafted polyol to a condensation reaction with a hydroxyl-functional polysiloxane, to obtain the polysiloxane-modified polyurethane. The polysiloxane-modified polyurethane can be used in a coating composition to form a coating which has smooth feel, stain resistance and easy clean properties, particularly desired in the field of e.g. consumer electronics and automotive industry.

摘要： The disclosure relates to a method of applying a coating to an external surface of a man-made object to be at least partly immersed in water (e.g. a vessel or an offshore drilling station) for a time period wherein there is relative movement between the immersed object and the water. The applied coating has a minimal resistance rating for a set of coatings. The method comprises a computer-implemented coating selection process, which comprises a first steps of obtaining, for each coating in the set of coatings, a total roughness value of the external surface based on a fouling roughness value, a macro roughness value and a micro roughness value associated with each coating. The coating selection process comprises in a second step selecting a coating from the set of coatings, wherein the selected coating has a minimal resistance rating associated with the obtained total roughness value for the time period. The method further comprises applying the selected coating to the external surface of the man-made object.

摘要： Corrosion and chip-resistant coatings for high tensile steel components, such as automotive coil springs, can be formed from a coating composition comprising a primer having an epoxy resin with the proviso that the epoxy resin does not have an EEW of about 860 to about 930, a polyhydroxyl functional phenolic curing agent having a HEW of about 200 to about 500, and a platy filler. The primer contains less than 20 wt % zinc. The topcoat includes an epoxy resin having an epoxy equivalent weight of about 450 to about 1400, an elastomer-modified epoxy resin having an epoxy equivalent weight of about 1000 to about 1600, a foaming agent and a reinforcing fiber.

摘要： The present invention relates to a process for repairing a coating film by applying an adhesion primer comprising a hydroxy-functional (meth)acrylate resin, a hydroxy-functional epoxy resin, a polyisocyanate, and an epoxy-functional organosilane directly to a substrate that is a substrate body with an original coating that has defects, to form an adhesion-promoting film and, applying at least one further layer of coating to the resultant adhesion-promoting film. The invention further relates to the use of the adhesion primer to improve the adherence of a further coating layer to such substrate, preferably to a substrate with a substrate body of glass fiber-reinforced unsaturated polyester resin, of glass fiber-reinforced epoxy resin, or of glass fiber-reinforced vinyl ester resin, wherein the further coating layer preferably is a polyurethane-based coating. The present invention further relates to a substrate coated with a coating film that has been repaired according to such a process.
