COIL-COATED SPECTRALLY SELECTIVE COATINGS ON COPPER OR ALUMIN WITH PIGMENTS MODIFIED BY AMINOSILANE

摘要

The invention relates to TSSS and TISS coatings applied by coil-coating onto substrates of copper or aluminum. Inorganic pigments functionalized by aminosilane are used for making paints, which after the coil-coating onto the substrate form the coatings. For the functionalization the pigment is dispersed in a solution of an aminosilane in a solvent or a mixture of a solvent and a binder without an addition of a non-aminosilane dispersing agent with or without subsequent grinding and use of 0.05-30 % of aminosilane on pigment. An aromatic, aliphatic, cycloaliphatic, ketone, ester, ether or alcohol compound or a mixture thereof can be used as the solvent. A silicone-polyester, polyurethane or fluoropolymer can be used as the binder.
