SiliaBond® pH Stability

Our SiliaBond functionalized silica gels are stable between a pH of 2 to 10.
At a pH below 2, the leaching of the bonded functions could be observed. The more the pH decreases, the more this phenomenon may occur. At a pH above 10, hydrolysis of the silica gel could occur. Under extreme conditions, the silica gel can be completely dissolved.

Watch this Q&A video explaining both leaching of the functions and hydrolysis of the silica particle:
