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.

摘要： The invention relates to formulations of aqueous dispersion adhesives based on aqueous polyurethane or polyurethane-urea dispersions, and to the use of the adhesive formulations for the adhesive bonding of foam substrates by the spray coagulation process. The dispersion comprises as disperse phase at least one polymer which after drying is semicrystalline or crystalline and has a melting temperature in the range from 30 to 80° C. and an enthalpy of fusion of ≥35 J/g. The formulation comprises at least one plasticizer and optionally at least one tackifier resin.

摘要： The invention relates to the use of solid polycarbodiimide resins having a softening temperature of >+30° C. as cross-linking agents for adhesive dispersions polymers. The mixtures from at least one solid polycarbodiimide resin and at least one polymer dispersion are suitable for producing storage stable latent-reactive adhesive dispersions, latent-reactive adhesive layers, self-supporting latent reactive adhesive films or latent-reactive adhesive powders.
