Silica Ph
Precipitated silica has both internal and external surface area, which allows for easy adsorption of liquids, among other qualities. Primary characteristics include:
pH
The pH of precipitated silica is normally slightly acidic (5.5-7.0). But
for defoamer applications, the pH is adjusted to the alkaline range to
ease the hydrophobizing process which most defoamer manufacturers employ.
