A coating material composition for providing coated films is disclosed. The coating material composition contains coated film forming resin (A), crosslinking agent (B), and resin beads (C), in which compression strength of the resin beads (C) at the time of the 10% pressurized deformation of an individual resin bead by means of a micro-compression tester lies between 0.1 MPa and 20 MPa and a recovery of the resin beads (C) following 90% pressurized deformation of an individual resin bead by means of a micro-compression tester is at least 80%.

The invention relates to a sandwich sheet metal, in particular for producing components or vehicle body parts, comprising metallic cover sheets (1.1, 1.2) and at least one core layer (1.3) which is located between the cover sheets, is made of polymer and is integrally joined to the cover sheets (1.1, 1.2). The core layer (1.3) of the sandwich sheet metal has a fibrous substrate and a polyurethane matrix that surrounds the fibres of the substrate, the polyurethane matrix being formed from an aqueous solvent-free polyurethane dispersion, the fibres being present in the polymer matrix as shorter fibre pieces having a maximum fibre length of 0 mm. The fibres of the substrate are preferably composed of mineral fibres, in particular of ceramic fibres. The sandwich sheet metal (1) as per the invention is characterised by a cost-efficient, light core layer that increases the potential uses of the sandwich sheet metal. A method for producing such a sandwich sheet metal is also disclosed.

[Problem] In a coating method of a two-coat one-bake system where a clear coat paint is coated after a base coat paint is coated, then these two coated layers are simultaneously hardened, adhesive strength between the two coated layers is to increase in comparison with the conventional method. [Solution] Provided is a coating method; A specific hardener is used in the clear coat paint. The hardener is one containing a polyisocyanate derived from 1,6-hexamethylene diisocyanate, satisfying all the following conditions: 1) Hardener does not virtually include diisocyanate monomer, 2) Viscosity of hardener is not more than 1000 mPa·s/23° C., 3) Content of HDI trimer in hardener is not less than 60 weight %, and 4) Content of HDI dimer in hardener is less than 10 weight %.

The invention relates to a white coated polyester film which has excellent adhesion to ethylene -vinyl acetate (EVA), which is typically used as an encapsulation material in solar modules. The good adhesion properties are achieved with a polymeric coating which comprises at least one polyurethane and a crosslinker.
