Patents by Inventor Ulrike Behrens

Ulrike Behrens has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20190337282
    Abstract: The present invention relates to a novel process for the production of coated filaments for subsequent application as print in extrusion-based 3D printers, e.g. FDM printers (fused deposition modelling printers). The filaments are coated in a separate process outside of the printer, and can also be used in a conventional extrusion printer. The present invention further relates to the coating device for application of the coating to the filament and to a roll containing the coated filaments.

  • Publication number: 20120065322
    Abstract: The present invention relates to a (meth)acrylate polymer for preparing a coating composition, where the (meth)acrylate polymer has a weight-average molecular weight in the range from 10 000 to 60 000 g/mol and the (meth)acrylate polymer comprises 0.5 to 40% by weight of units derived from (meth)acrylic monomers which in the alkyl radical have at least one double bond and 8 to 40 carbon atoms, 0.1 to 10% by weight of units derived from monomers containing acid groups, and 50 to 99.4% by weight of units derived from (meth)acrylates having 1 to 12 carbon atoms in the alkyl radical that have no double bonds or heteroatoms in the alkyl radical, and these (meth)acrylates having 1 to 12 carbon atoms in the alkyl radical are selected such that a polymer composed of these (meth)acrylates having 1 to 12 carbon atoms in the alkyl radical has a glass transition temperature of at least 40° C., based in each case on the weight of the (meth)acrylate polymer.

  • Publication number: 20100062271
    Abstract: The invention relates to a process for preparing binders for plastisols that ensures high and consistent product quality over a multiplicity of batches. The binders obtained from this process allow the formulation of plastisols which possess improved stability on storage and, after gelling, improved mechanical properties.
