  • Patent number: 11072671
    Abstract: Described herein is a process for making PTFE having a standard specific gravity of less than 2.160 g/cm3 comprising: polymerizing a tetrafluoroethylene monomer in an aqueous medium comprising an emulsifier and an initiator in a reaction vessel and contacting the aqueous medium with a fluorinated polyether. Also described herein are the polymerizable compositions and articles thereof.

  • Publication number: 20200208088
    Abstract: The present invention relates to a microtissue compartment device, comprising a compartment structure (1) having an upper surface (2) and a lower surface (3) essentially coplanar thereto, and at least two wells (4) suitable for accommodating one or more microtissues (5) in a liquid volume, each well having a lower section (4a) with a given diameter, coaxially oriented thereto an upper section (4b) with an extended diameter, and at least one conduit (6) fluidically connecting at least two wells to one another, and at least one space (13) arranged above a well. At least one well has, in its upper section, a relief structure (9) that prevents spreading or overflow of a liquid volume comprised in said well into space (13).

  • Patent number: 9139668
    Abstract: There are provided compositions comprising (i) at least one non-aromatic polyol compound containing at least one polyol unit having at least two hydroxyl groups and at least one long chain unit containing at least 6 carbon atoms; and (ii) at least one fluoropolymer comprising repeating units derived from a fluorinated olefin. There are also provided methods of improving the shear stability of fluoropolymer dispersions, methods of coating substrates, and substrates coated with the above described composition.

  • Patent number: 7147471
    Abstract: A method for treating hard tissue infection in a site-specific manner, comprising preparing a negative mold of the hard tissue using an impression material which contains a diagnostic additive which generates an identifiable signal on contact with infected tissue; applying a treatment agent to the negative mold at one or more of infected sites; and re-applying the negative mold on the originally molded hard tissue for a suitable period of time. Also disclosed are methods for making the negative mold, a mouthpiece corresponding to the negative mold, and a treatment device, as well as the treatment device and mouse piece so produced.

  • Patent number: 7097456
    Abstract: The invention relates to filling systems containing as component i) a sealing system which is capable of bonding to the tooth hard substance, as component ii) a filling material suitable for restorative dentistry, the filling system containing in addition a component iii) in component i) and/or component ii) which reduces the curing of the respective other component by disturbance of the curing mechanism only in the boundary layer between sealant and filling material such that the bonding between components i) and ii) is less than the bonding of component i) to the tooth hard substance.

  • Patent number: 6752989
    Abstract: The invention concerns surface treatment agents for hard tissue, including at least one enzyme and an agent inhibiting the enzyme activity, whereby the surface treatment agent remains on the hard tissue during the application.

  • Patent number: 6245872
    Abstract: The invention relates to the use of a mixture in a process for the adhesive securing of dental filling materials, comprising i) 10 to 90 parts by weight of at least one singly or repeatedly ethylenically unsaturated phosphoric acid ester, ii) 5 to 85 parts by weight of a solvent, iii) 0.01 to 5 parts by weight of an initiator which can form free radicals, and iv) 0 to 10 parts by weight of customary auxiliaries and additives, coating with polymerizable filling material being carried out immediately after the application of the mixture to the hard tooth substance. The invention offers the advantage that the mixture is applied to the hard tooth substance in one step and, unlike the state of the art, is coated with polymerizable filling material immediately without further aftertreatment and leads to adhesive joins comparable to those in the state of the art.
