  • Patent number: 9393381
    Abstract: A cover unit for inserting a puncture device such as a cannula in an anatomical structure such as a vein or an artery and for maintaining said puncture device in said anatomical structure, comprising a flexible film having a glue provided surface, and a removable covering layer to cover said glue provided surface, wherein said cover unit comprises a patient adherent member and a barrier member connected along a connection line, which is arranged close to a puncture site in a patient; said film being made of an ultrasound transparent material; said barrier member being provided with at least one slit or weakening line extending from next to said connection line to a side edge of the cover unit and provided in said film; and said covering layer in the barrier member is removable from the film separately from the corresponding covering layer in the patient adherent member.

  • Patent number: 9175185
    Abstract: What are described are coating compositions comprising pigments and/or fillers and multistage polyvinyl ester dispersions as binders. These binders are produced by a selected multistage process in which a polyvinyl ester dispersion is obtained in a first stage, monomers in dissolved or pure form or in the form of an emulsion are added to the reaction mixture in a second stage and then the polymerization is started again. The polyvinyl ester dispersions comprise polymerized silanes and/or epoxides or the polyvinyl ester dispersions have only a small content of protective colloids, if any. The coating compositions formulated with the multistage polyvinyl ester dispersions obtained in this way are notable for a very high weathering resistance.

  • Patent number: 9029469
    Abstract: A wood protection paint comprises a copolymer emulsion prepared by an emulsion polymerization process, in which a first monomer composition comprising from 60 weight percent to 95 weight percent of at least one vinyl ester, and from 5 weight percent to 40 weight percent ethylene is polymerized in a first stage under ethylene pressure to produce a first stage product having a Tg of less than 25° C. Then, in a second stage, a second monomer composition selected such that the polymer produced by the second monomer composition has a Tg of at least 95° C.

  • Publication number: 20140350172
    Abstract: In a multi-stage emulsion polymerization process, a first monomer composition comprising from about 60 weight percent to about 95 weight percent of at least one vinyl ester, and from about 5 weight percent to about 40 weight percent ethylene is polymerized in a first stage under ethylene pressure to produce a first stage product having a Tg of less than 20° C. Then, in a second stage, a second monomer composition comprising at least 95 weight percent of a meth(acrylic)ester or a mixture of at least two different (meth)acrylic esters is polymerized in the presence of said first stage product, wherein the (meth)acrylic ester(s) is selected such that the polymer produced by said second monomer composition has a Tg of 5 to 90° C.

  • Patent number: 8436088
    Abstract: Plasters and renders and paints, copolymer dispersions and their use Compositions containing selected polymer dispersions, colloidal silica, fillers and pigments are described. These can be formulated to give plasters and renders or paints which are distinguished by excellent abrasion resistance, little tendency to soiling, high water vapor permeability, good adhesion and good weathering stability. The compositions according to the invention can be processed to give plasters and renders or paints which have a nanostructured surface and which differ from conventionally produced surfaces.
