Résumé : |
A significant enhancement of fluorine content at the air interface in polyester melamine coatings was achieved by the utilisation of surface-migrating polyfluorooxetane copolymer moieties. The manipulation of the microstructure of the fluorinated polyesters was conducted by utilising a design of experiments (DOE) to quantify and optimise the performance of polyester melamine coatings through the manipulation of the non-cyclic monomer level, the polyfluorooxetane level, the choice of aromatic monomer, and the functionality of the polyester. Changes in stain, solvent and scratch resistances corresponding with the composition of the polyfluorooxetane-modified polyesters were demonstrated. |
