Study of application temperature and joint thickness impact on fast fixing effect of one component PUR adhesives

Temperature, time (waiting time after the application of adhesive; curing time total time for the adhesive to gain complete strength) that impact on the rheological properties has shown interest in the field of research. The core of this thesis was to focus on the thickness of joint and application temperature dependence of one-component polyurethane (PUR) moisture curable adhesive on fast fixing effect of the adhesive.The impact of rheological properties on the adhesive bond were investigated by Ubbelohde method (Viscosity test), differential scanning calorimetry (DSC), temperature profiles and gangel tests. These tests were also conducted to observe fast fixing effect of the adhesives. From the results, it was observed that viscosity and application temperature of the adhesive could influence the strength of bonded plastic parts. For higher efficiency of the bond, the processing parameters should be optimized.Temperature, time (waiting time after the application of adhesive; curing time total time for the adhesive to gain complete strength) that impact on the rheological properties has shown interest in the field of research.
