  • Patent number: 10961409
    Abstract: The present invention relates to aqueous binders and to heat-sealing lacquers produced therefrom for heat-sealable coatings which adhere on aluminium without use of any primer, permit good sealability of the coated aluminium foil with respect to PS and/or PVC, and moreover feature good blocking resistance even at temperatures above 40° C.

  • Patent number: 10385244
    Abstract: The present invention comprises a single-component binder for heat-sealing applications which can be used for the sealing of polyester foils, in particular of polyethylene terephthalate foils (PET foils) with respect to containers made of polystyrene, of PVC, and of polyester. These polyesters can in particular be polyethylene terephthalate (PET) or polylactic acid (PLA). The binders here feature not only good seal seam strengths but also in particular good transparency and excellent application properties. A substantive aspect of the invention is that the sealing can be achieved without addition of adhesion promoters, in particular without addition of adhesion promoters based on polyvinyl chloride (PVC) or on polyester, and that barrier properties and sealing properties achieved in respect of containers made of PS and of PET are nevertheless at least comparable with, and sometimes better than, those achieved with heat-sealing systems already marketed.

  • Patent number: 10195829
    Abstract: A transparent, heat-sealable coating for transparent PET packaging foils can be provided by using a heat-sealable lacquer based on styrene-containing copolymers, on poly(meth)acrylates, on at least one polyester and optionally on a tackifier, and also the process for the sealing of a foil coated with this lacquer. It is surprising here that, despite the use of a rubber based on styrene-containing polymers that is not optically compatible with polyesters and polymethacrylate, the transparency of the heat-sealable coatings is still very high.

  • Patent number: 9701588
    Abstract: The present invention relates to a novel process for producing ceramic materials, in particular refractory materials having a reduced relative density. In particular, the invention relates to a process for producing light, refractory materials having non-contiguous pores based on shaped and unshaped materials. These materials can be used as working lining in high-temperature applications. The process is based on the production of spherical, closed and isolated pores in the microstructure of the material. The pores having a pore diameter which can be set in a targeted manner are generated by use of polymer particles, in particular polymethacrylates, in particular polymers or copolymers prepared by means of suspension polymerization, as pore formers which can be burnt out. The polymers or copolymers are present in the form of small spheres having a defined diameter.

  • Publication number: 20040072686
    Abstract: A shaped metal fixed-bed catalyst is disclosed which is made from at least one catalyst alloy formed of a catalyst metal and an extractable alloying component. The catalyst is activated in an outer layer with a thickness of 0.1 to 2.0 mm, starting from the surface, by complete or partial extraction of the extractable alloying component. The catalyst may also contain promoters. The catalyst is distinguished from known catalysts in that it is formed exclusively of the catalyst alloy and is free of alpha-aluminum oxide, and has a total pore volume of 0.1 to 0.6 ml/g and a bulk density lower than 2.2 kg/l. The catalyst is used for hydrogenation, dehydrogenation and hydrogenolysis reactions.
