  • Patent number: 10196752
    Abstract: The present invention relates to a method for producing a multicoat paint system on a metallic substrate, in which a basecoat or a plurality of directly successive basecoats are produced directly on a metallic substrate coated with a cured electrocoat, a clearcoat is produced directly on the one basecoat or the uppermost of the plurality of basecoats, and then the one or more basecoats and the clearcoat are jointly cured, and wherein at least one basecoat material used for production of the basecoats comprises at least one linear hydroxy-functional reaction product (R) having an acid number of less than 20 mg KOH/g, the preparation of which involves using at least one compound (v) containing two functional groups (v.1) and an aliphatic or araliphatic hydrocarbyl radical (v.2) which is arranged between the functional groups and has 12 to 70 carbons atoms.

  • Patent number: 9546285
    Abstract: The invention relates to coating compositions based on organic solvents and comprising at least one hydroxyl-containing compound (A), at least one crosslinking agent (B) having groups reactive toward hydroxyl groups, and at least one silica gel based matting agent (M), wherein (i) the matting agent (M) is surface-modified with one or more waxes, and (ii) the coating composition further comprises at least one hydrophobic silica based rheological assistant (R). The present invention further provides multistage coating methods using these coating compositions, and also the use of the coating compositions as clearcoat or application of the coating method for automotive OEM finishing, for the finishing of parts for installation in or on automobiles, and for automotive refinishing.
