PURPOSE: Ozone safe fluorine resin ozone proof paints are provided to improve an adhesive power between layers using surface preparation materials, and to have an excellent adhesion to moisturized concrete using a silane modified primer. CONSTITUTION: Ozone safe fluorine resin ozone proof paints comprise: a silane modified primer(10), a surface preparation material(20), ceramic modified clycidyl layers(31,33), and an ozone safe fluorine modified resin layer(35). The silane modified primer comprises a main material and a curing agent in a ratio of 4:1 by wt%. The main material comprises tetraethoxysilane(TEOS) and prepolymer of silane modified acryl polymer compound. The curing agent is a silane compound having amino-silane. The surface preparation material comprises: (a) a mixture of bisphenol F type of epoxy, silane modified acryl prepolymer and TEOS, (b) a mixture of amino-silane and an amine type of curing agent, and (c) inorganic powder in a ratio of 1:2.5:8 by wt%. The ceramic modified clycidyl layer comprises a main material and a curing agent. The main material comprises bisphenol F type of epoxy resin, TEOS, aliphatic epoxy resin, circular-aliphatic epoxy resin, etc. The curing agent comprises aliphatic polyamine curing agent, anhydride curing agent, etc. The ozone safe fluorine modified resin layer comprises 100 wt% of acryl urethane and 1-10 wt% of fluorine resin.
