| abstract |
The invention relates to a method for applying a material containing a molten polymer, comprising the step of applying a filament of the at least partially molten material containing a meltable polymer from a discharge opening of a discharge element in a first substrate. The molten polymer has the following properties: a melting point (DSC, differential scanning calorimetry; second heating at a heating rate of 5°C/min) in a range of >=35°C to <=150°C; and a glass transition temperature (DMA, dynamic mechanical analysis according to Din in ISO 6721-1: 2011) in a range from >= -70°C to <= 110°C; the filament having an application temperature of >= 100°C above the melting point of the meltable polymer for <= 20 minutes during the application process. Furthermore, NCO groups are present in the material containing the meltable polymer. (Automatic translation with Google Translate, without legal value) |
