Ultraviolet curable optical pick-up adhesive composites composed of acrylic and methacrylic mono-, bi- and trifunctional monomers and two kinds of urethaneacrylate oligomers have been easily prepared. In this paper, we studied the influence of various silane coupling agents to enhance the adhesion property in thermal and humid conditions by acting as both inorganic surface and organic polymer modifiers. Among them, vinyltriethoysilane (VTES) provides good adhesion effects on acrylate binder as well as silica surface. VTES added adhesives were studied by the real time FT-IR. The reliability of adhesives was explained by thermal-mechanical analysis (TMA) and then durability was tested by water boiling test. These UV-adhesives were successfully applied and settled in CD and DVD optical pick-up bodies in commercial application.
