<p><P>PROBLEM TO BE SOLVED: To provide a silicone coating composition whose coated cured film expresses mar resistance, and UV-shielding property while maintaining visible light transparency, and further simultaneously has weatherability durable against long term out-door exposure and durability, and a coated article using the same. <P>SOLUTION: The UV-shielding silicone coating composition comprises (A) a dispersion in a dispersing medium of composite zinc oxide fine particles which are obtained by coating the surface of the zinc oxide fine particles with at least one kind selected from an oxide or hydroxide of Al, Si, Zr and Sn, the dispersion having a photocatalytic degradability of up to 25%, (B) a silicone resin, (C) a curing catalyst, and (D) a solvent, the solids content of composite zinc oxide nanoparticle dispersion (A) being 1 to 50 mass% based on silicone resin (B). <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
