Abstract: Silica sol/hydroxypropyl acrylate hybrid sol was synthesized and the super-hydrophilic coatings for the auto-glass surface were prepared by UV curable technology. The contact angle of coating was lower than 5° and the pencil hardness of the coating reached 5H. The influence of concentration of silica sol and content of hydroxypropyl acrylate on the hydrophilic property, surface hardness and appearance of the film were discussed. The composition and micro-structure of the coatings were characterized by means of XPS,FT-IR and SEM, the influence of which on the film performance was discussed.
