NOVELTY - Solvent (a) (in parts weight) (14.5-29.7), fluorinated ethylene vinyl ether resin (30-50), anti-settling agent (0.3-0.5), wet dispersing agent (4-5) and pigment (15-50) are mixed in a container, stirred, glass ball (100-120) is added to reaction mixture, and ground, to obtain color paste. Then, fluorinated ethylene vinyl ether resin (25-70) and amino resin (10-15) are stirred, solvent (b) (9-14.5), auxiliary agent (0.5), polishing powder (0-0.5) and color paste (0-50) are added to reaction mixture, dispersed, and filtered, to obtain fluorocarbon coated material.    USE - Manufacture of fluorocarbon coated material used for polyethylene terephthalate film for solar-battery back board (all claimed).    ADVANTAGE - The fluorocarbon coated material having excellent weather resistance, water-vapor permeability and insulating property is manufactured. The solar-battery back board has excellent storage stability and durability.    DETAILED DESCRIPTION - Solvent (a) (in parts weight) (14.5-29.7) is added to a container, stirred at low speed, and fluorinated ethylene vinyl ether resin (30-50), anti-settling agent (0.3-0.5), wet dispersing agent (4-5) and pigment (15-50) are added to the container, stirred uniformly, glass ball (100-120) is added to the reaction mixture, and ground at high speed until the fineness is 20-25 mu m, to obtain color paste. Then, fluorinated ethylene vinyl ether resin (25-70) and amino resin (10-15) are added to a container, stirred at low speed, solvent (b) (9-14.5), auxiliary agent (0.5), polishing powder (0-0.5) and color paste (0-50) are added to the reaction mixture, dispersed at high speed for 15-20 minutes, and filtered, to obtain fluorocarbon coated material. INDEPENDENT CLAIMS are included for the following:    (1) fluorocarbon coating material; and    (2) usage of fluorocarbon coating material, which involves pre-treating polyethylene terephthalate film, coating fluorocarbon coating material on the pretreated polyethylene terephthalate film using double-roller coating machine, drying at 160-165 degrees C for 3-5 minutes, and rolling.
