The influencing factors of preparation technology for KH560 silane films were studied, including ponents, structures, adhesive strength of film, and the hydrolysis degree of KH560 coupling agent. ponents and structures of KH560 silane film were analyzed by the reflection-absorption infrared spectroscope, the hydrolysis degree of KH560 coupling agent was measured by the conductivity testing method on-line, and the film adhesive strength was inspected by pull-off testing method. The results indicated that the properties of the film were significantly affected by hydrolysis solvent, hydrolysis time, concentration
