Figure 3. Activation (hydrolysis) of the experimental silanes. (a) Hydrolysis of 0.1% 3-isocyanatopropyltriethoxysilane. A: t = 0 min, B = 30 min, C = 60 min. X-axis: wave number (cm^–1) and Y-axis absorbance A (in arbitrary units). (b) Hydrolysis of 1.0% 3-methacryloyloxypropyltrimethoxysilane. A: t = 0 min, B = 30 min, C = 60 min. X-axis: wave number (cm^–1) and Y-axis absorbance A (in arbitrary units).
