Why Titanates and Zirconates May Be Better Adhesion
The reason why titanates and zirconates may be better adhesion promoters than silanes lies in the intrinsic multifunctional chemistry of organometallic titanium and zirconium as compared to silicone at the nano-interface where dissimilar materials meet (Figure 1). If you look at the periodic table according to atomic nuer, there seems to be little in common between Si, Ti and Zr (Figure 2a).
