| Résumé : |
The decorative service life of architectural exterior coatings is often determined by the onset of large colour shifts or visible chalking of the coating. Here, the authors report three-year Florida and accelerated weathering results for a series of 70% poly(vinylidene fluoride) (PVDF) coatings made with a palette of relatively weatherable organic pigments. Many of these coatings show minimal visible colour change after three years in Florida, and 6000 hours accelerated weathering. Surprisingly, the more aggressive UV-B bulb exposure, unlike UV-A bulb exposure, shows a high degree of statistical correlation with the three-year colour shift in Florida. For most of these systems, UV absorber/HALS (hindered amine light stabiliser) packages do not improve the performance, but a 70% PVDF clear coat does. |
