摘要： 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.-
