Abstract (en)
[origin: WO2019224286A1] To achieve anti-fingerprint properties to decorative surfaces, a novel method for coating a metal substrate with an anti-fingerprint coating is provided. The method comprises the following method steps: (a) providing the metal substrate; (b) providing a silicone coating mixture containing: (i) at least one first silicone compound selected from the group consisting of mono- or oligo(aminoalkyl)-fluoroalkyl silicones; (ii) at least one second silicone compound selected from the group consisting of aminoalkyl silicones; (iii) at least one acidifier; and (iv) water; further (c) treating the metal substrate with the silicone coating mixture by bringing the metal substrate into contact with the silicone coating mixture; and (d) curing the treated metal substrate at a predetermined temperature.
