Publication number: 20230120483Abstract: An innovative reactive resin system can be used for intumescent coating. Intumescent coatings are used in particular for fire protection of metallic components, such as girders in structural engineering. In a fire scenario, these coatings are reactively foamed and so form a fire-resistant insulating layer with low thermal conductivity around the metal girder, with the resultant insulation retarding premature failure of this component. The resin systems are prepared by an innovative process where the monomer fraction is polymerized only up to a maximum degree of 70%. The glass transition temperature of this polymeric component of the resultant composition is particularly low.Type: ApplicationFiled: February 26, 2021Publication date: April 20, 2023Applicant: Röhm GmbHInventors: Bruno Keller, Sven Balk

Patent number: 10961409Abstract: 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.Type: GrantFiled: August 29, 2018Date of Patent: March 30, 2021Assignee: Evonik Operations GmbHInventors: Florian Hermes, Dominik Sturm, Christian Golditz, Michael Wicke, Herbert Jung, Juergen Hartmann, Bruno Keller

Patent number: 10385244Abstract: 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.Type: GrantFiled: May 7, 2015Date of Patent: August 20, 2019Assignee: Evonik Roehm GmbHInventors: Andre Hennig, Thomas Arnold, Michael Wicke, Juergen Hartmann, Bruno Keller, Guenter Schmitt, Michael Waldhaus

Patent number: 10195829Abstract: 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.Type: GrantFiled: May 17, 2017Date of Patent: February 5, 2019Assignee: Evonik Roehm GmbHInventors: André Hennig, Bruno Keller, Juergen Hartmann, Thomas Arnold, Michael Waldhaus, Monika Maerz

Patent number: 9701588Abstract: 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.Type: GrantFiled: February 26, 2016Date of Patent: July 11, 2017Assignee: Evonik Roehm GmbHInventors: Tadeusz Von Rymon Lipinski, Bruno Keller, Frank Beissmann, Peter Neugebauer, Ruth Kernke, Dirk Poppe
