High-concentration colloidal silica( silicon dioxide, silica sol)GS-40, GS-35 are two types of high-concentration colloidal silica. Their technical standards are listed below Designation StandardGS-40GS-35AppearanceSlight milky transparent to translucentSiO2 (wt%)40±1%35±1%Na2O (wt%)≤0.7%≤0.5%PH (20°C)9.5-10.59.0-11.0Density (20°C,g/cm3)1.280-1.2951.24-1.25Viscosity(25°C,mPaS)10-35 ≤20 Particle size (nm)10-15 8-20 Packing & Storage Colloidal silica is packed in 25kg,250kg or 1000kgplastic drums. Store the colloidal silica at a temperature between 0 and 50, avoid exposure to the air, and insulate it from the sun. Wash the empty drums as quickly as possible to avoid SiO2 crystalline deposits. If you want to remove the deposition from empty drums, use a 10-percent NaOH solution at 50 60.
