  • Patent number: 9931524
    Abstract: A metallic effect pigment with an additive, the additive being applied on at least a portion of the metallic effect pigment. The additive comprises, as structural units, at least one carboxylic acid having at least 4 carbon atoms and also at least one polyglycol ether. The carboxylic acid and the polyglycol ether are bonded covalently to one another. The disclosure is also directed to a method for producing these metallic effect pigments, and to the use thereof, as well as to a printing ink comprising the pigments.
    Type: Grant
    Filed: May 28, 2009
    Date of Patent: April 3, 2018
    Assignee: ECKART GMBH
    Inventors: Dieter Proelss, Stefan Trummer, Stephan Roth, Bärbel Gertzen, Wolfgang Pritschins, Jürgen Omeis
  • Patent number: 9850373
    Abstract: The invention relates to a composite formulation comprising a specific mediator additive component (A) of relatively high molecular weight, a filler component (B) and a binder component (C). The composite formulation can be cured to a composite which is especially suitable for the production of moldings.

  • Patent number: 9556299
    Abstract: The invention relates to a copolymer whose overall structure as such and/or an optionally present segment A having at least 10 bivalent structural units in the overall structure contains surface-active bivalent structural units present in the form of long hydrocarbon chains among other forms. The copolymer is effective as a universal surface-active additive, especially also in conjunction with nonpolar media.

  • Patent number: 8956660
    Abstract: The invention relates to a method for producing particulate composite materials. According to the method, solid inorganic or organic particle agglomerates or particle aggregates that are provided in a dry state, particularly in powder form, are first reduced in size in the gas phase or in a gaseous carrier medium in the presence of organic matrix particles by applying energy. The obtained comminuted particles are dispersed into the organic matrix particles, especially embedded thereinto and/or attached thereto. The composite materials produced in said manner can be used in many different ways and are suitable in particular for use in a large variety of plastic materials, coating materials, paints, and lacquers, especially coating powders, to modify properties during use in the corresponding products and similar.

  • Publication number: 20060270795
    Abstract: The invention relates to an unsaturated polyester resin mixture which can be cured by applying external pressure and which encompasses at least the following components: a) an unsaturated polyester resin whose weight-average molar mass is from 500 to 5000 g/mol; b) an ethylenically unsaturated monomer; c) a shrinkage-reducing component; d) an inert filler; and e) a reinforcing fibre; and f) from 0.01 to 1% by weight of a block copolymer, based on the total weight of the unsaturated polyester resin mixture comprising reinforcing fibre, where the block copolymer encompasses at least one A block and encompasses at least one B block, where the A block contains at least one amine-containing, ethylenically unsaturated monomer; and the B block contains at least one alkyl- and/or phenyl-containing, ethylenically unsaturated monomer, and is free from amine-containing, ethylenically unsaturated monomers.

  • Patent number: 6870024
    Abstract: The invention relates to a polymeric urea-urethane obtainable by first reacting a diisocyanate with a polyol to form a doubly NCO-terminated urethane prepolymer. Further reaction is subsequently carried out with a mixture of a primary monoamine and a primary diamine. After the second reaction the polymeric urea-urethane present is substantially free of isocyanate and of the monoamine and diamine used. It can be used as an agent for controlling the rheology of liquid polymers or polymer solutions.
