Abstract: This paper describes the type of waterborne PVDF resin, the basic formulation of waterborne PVDF coatings and the film-formin temperature. The properties of the prepared coatings are investigated. Meanwhile, a comparison of accelerated weathering resistance performance between waterborne PVDF coatings and solvent-based ones has been carried out.The results show that the waterbome and solvent-based PVDF coatings exhibit the similar weatherability which meets the AAMA 2605-2013 Specification. Besides, the waterborne PVDF coatings can be cured at low temperature. The effects of coating temperature and humidity on the appearance of the PVDF coatings are also examined so as to obtain the suitable parameters for good coating process.
