| Abstract: | The modified silicone sol from TEOS and MAPTMS were used as inorganic components and hyperbranched polyurethane acrylate（HBPUA）were used as organic components for preparing UV-curable HBPUA/（MAPTMS-SiO2） hybrid coatings. When nSiO2：nMAPTMS=1：2, the content of modified silicone sol was 30 ω/%, the hybrid coatings had optimal properties with the gel time of HBPUA/（MAPTMS-SiO2） hybrid coatings exceed 180 days, transmittance of 92.8 %, pencil hardness of 4H, adhesion of 0 degree, flexibility of 3 mm, impact strength of 46 kg.cm and abrasion resistance of only 17.5 mg. |
