Perfluoroalkoxy copolymer coated glass and method of manufacturing same

Abstract

An apparatus and method for coating glass, and specifically to perfluoroalkoxy copolymer coated glass and a method for manufacturing same. A glass substrate is placed on an electrically grounded support and cleaned with a solvent to remove impurities and prepare the surface of the substrate to be coated. The surface is coated with a primer and an electro-conductive enhancer is uniformly applied to the primer so that the surface of the glass substrate is wet, but not uneven. The perfluoroalkoxy copolymer is powder sprayed on the electro-conductive enhancer while the enhancer is still wet. The perfluoroalkoxy copolymer is secured to the glass substrate by evaporating the electro-conductive enhancer.
