2.Dusts on coating surface are removed by air ionizing blowers
3.Electrostatic spray applied flash primer with dry film thickness 5~8 microns.
3.Electrostatic spray applied PVDF top coat with dry film thickness 25~30microns
4.Coated parts are thermal cured with metal surface temperature 230~240 degree for 10~15 mintues.
5.Quality inspection for coating layer.
6.As PVDF coating,our PVDF DS203 has fine chemistry corrosion resistance,ultraviolet ray resistance as well as the high energy radiativity resistance etc.It is the best coating for Aluminium products.
