Silica sol Technical Sepecifitation Model:P100ASiO2(%):40%Stability:12MonthsAppearance:Milky White liquidPH (25degree Celsius):9-11Diameter of Partical:100-120nmViscosity(25 degree Celsius, mPaS):10Na2O (wt%):0.5%Delivery Time:Within 20 daysPalce of Origin:ChinaThis kind of silica sol is used as alkali chemical polishing solution. Characteristics1 colloidal Silica belongs to ordinary chemicals.2 It is milkywhite, tasteless and non-toxic.3 Its chemical molecular formula is mSiO2.nH2O.4 With low viscosity, it can soak the places where water soaks, therefore, it shows excellent dispersion and permeability when mixed with other substances.
