  • Patent number: 9777160
    Abstract: The invention relates to copper-containing metal pigments, wherein the copper-containing metal pigments have an elemental copper content of at least 50 wt.-%, relative to the total weight of the uncoated copper-containing metal pigment, wherein the copper-containing metal pigments have at least one enveloping metal oxide layer and at least one enveloping chemically non-reactive plastic layer, wherein the sum of the amounts of the at least one chemically non-reactive plastic layer and of the at least one metal oxide layer lies in a range of from 10 to 50 wt.-%, relative to the weight of the uncoated metal pigment, and the weight ratio of the at least one metal oxide layer to the at least one chemically non-reactive plastic layer lies in a range of from 1:2 to 1:20. The invention furthermore relates to a method for producing these pigments and the use thereof.

  • Patent number: 9580787
    Abstract: The invention relates to the use of a particle-containing powdered coating material in a coating method selected from the group consisting of cold gas spraying, flame spraying, high-speed flame spraying, thermal plasma spraying and non-thermal plasma spraying, wherein the particles have a relative deformability factor Vm of at most 0.1 and the relative deformability factor is defined according to Formula (I): V m = d D 50 , ( I ) wherein d is the average smallest thickness of the particles, measured vertical to and in the middle half of the longitudinal axis of the particles, and D50 is the average diameter of the volume-averaged particle-size distribution. The invention furthermore relates to a method for coating.

  • Patent number: 9260584
    Abstract: A coated wet-chemically oxidized aluminum effect pigment is provided having at least one metal oxide layer having at least one metal oxide which differs from aluminum oxide and an enveloping organic polymer layer, wherein the weight ratio of the metal oxide of the metal oxide layer to aluminum oxide in the wet-chemically produced aluminum oxide layer of uncoated wet-chemically oxidized aluminum effect pigment is in a range of from 1:1 to 1:40. Also, a method for the production of the pigment is provided.
