Product characteristics
Alkaline silica sol is a colloidal solution of amorphous silica particles of different sizes in water. Its pH value ranges from 9 to 11. It is called alkaline silica sol. Its molecular formula is mSiO 2.nH 2.O The particle size can be controlled at 7-15 nanometers.
1. It has large specific surface area and good adsorbability.
2. It has good adhesion, high temperature resistance, good hydrophilicity and oil repellency.
