ABSTRACT:
A method for coating glass, and specifically for manufacturing perfluoroalkoxy copolymer coated glass and tetrafluoroethylene perfluoromethyl vinyl ether copolymer coated glass. The method includes placing a glass substrate on an electrically grounded support and cleaning it with a solvent to remove impurities and prepare the surface of the substrate to be coated. The method also includes coating the surface with a primer and uniformly applying an electro-conductive enhance to the primer so that the surface of the glass substrate is wet, but not uneven. The method includes powder spraying periluoroalkoxy copolymer or tetrafluoroethylene perfluoromethyl vinyl ether copolymer on the electro-conductive enhancer while the enhancer is still wet. The method also includes securing the perfluoromethyl vinyl ether copolymer to the glass substrate by evaporating the electro-conductive enhance.
