Abstract: An adhesive composition includes a polyurethane polymer, a solvent and a co-solvent. The polyurethane polymer is an internally and/or externally hydrophilized thermoplastic polyurethane having a mass average molecular weight Mw, as determined by gel permeation chromatography against polystyrene standards using N,N-dimethyl acetamide as the eluent, of ?50000 g/mol, the solvent is a polar-aprotic solvent such as MEK and the co-solvent is water. The polyurethane polymer, the solvent and the co-solvent are present in such amounts that they form a dispersion. The polyurethane polymer content is ?10 weight-%, based on the total weight of the composition and the weight ratio of solvent to co-solvent is in a range of ?1:1 to ?4:1.

Abstract: An adhesive composition includes a polyurethane polymer, a solvent and a co-solvent. The polyurethane polymer is an internally and/or externally hydrophilized thermoplastic polyurethane having an Mw of ?50000 g/mol. The solvent is a polar-aprotic solvent. The co-solvent is selected from water, a primary alcohol having ?10 carbon atoms, a vicinal diol or a mixture of at least two of the aforementioned compounds. The solvent and the co-solvent are present in such amounts that they form a homogenous mixture without the formation of a second phase when combined together at 20° C. The hydroxyl group content is ?1 weight-%, based on the total weight of the composition. The polyurethane polymer content is ?10 weight-%, based on the total weight of the composition and the composition forms a single continuous liquid phase. Examples for solvent/co-solvent combinations are methylethyl ketone (MEK) and water or MEK and ethanol.

Abstract: The present invention relates to a method of manufacturing a solids-incorporating polymer comprising the steps of: I) providing an aqueous polymer dispersion, the dispersion comprising crystallizing polyurethane particles having a mean particle size of ?500 nm and further comprising inorganic particles; II) storing the dispersion of step I) at a temperature of ?0° C. until a precipitate is formed; III) Isolating the precipitate of step II) and IV) removing water from the isolated precipitate of step III), thereby obtaining a water-depleted precipitate. The invention also relates to a solid particulate composition which is obtainable by the method and the use of the composition as a build material in additive manufacturing processes, as a coating, an adhesive or as a rubber.

Abstract: A method of applying a material comprising a fusible polymer comprises the step of: applying a filament of the at least partly molten material comprising a fusible polymer from a discharge opening of a discharge element to a first substrate. The fusible polymer has the following properties: a melting point (DSC, differential scanning calorimetry; 2nd heating at heating rate 5° C./min) within a range from ?35° C. to ?150° C.; a glass transition temperature (DMA, dynamic-mechanical analysis to DIN EN ISO 6721-1:2011) within a range from ??70° C. to ?110° C.; wherein the filament, during the application process, has an application temperature of ?100° C. above the melting point of the fusible polymer for ?20 minutes. There are still free NCO groups in the material including the fusible polymer.
