Tasks*project description*:the coating process is the chemical reaction between the polyurethane resins (pu) and a crosslinker.
this chemical reaction changes the thermoplastic nature to thermoset of the pud, changing also the mechanical properties.
the knowledge about the crosslinker reaction leads to avoid issues due potlife and the printing machine parameters could me optimized (temperature and time).
the methodology used in this project can be used in future coating developments to increase the robustness of them as a standard test plan.a parallel benefit is the chemical characterization of the main pud resins and crosslinkers used in ssl, in slp location this information will be useful in the generation of the master specification data sheets and can be shared to other ssl locations that use similar systems*project deliverables*:- database of kinetic data of pu resins and crosslinkers (ea, kn).- ir spectrum of pu resins and crosslinkers analyzed.- standard test plan for coating crosslinker reaction rate.- written results in thesis format of the results according scientific method (hypothetico-deductive) with data and results that can be published.- research article (desirable).
*main tasks*:- search adequate information about crosslinker reactions in literature.- taking and interpretation of ir spectrum.- database creation for chemical structure for pu resins and crosslinkers.- monthly written reports about the findings and updates in project.
