More Information
Summary:A silica sol having a silica particle size/average primary particle size ratio measured by dynamic light scattering of 3.0 or lower, the silica sol containing silica particles having an average primary particle size of 20-100 nm surface modified by an organic silane compound having ±-ray emission of 0.005 count/cm 2 ·hr or less and a coefficient of moisture absorption of 0.5 mass% or less when allowed to stand for 48 hours in a 23°C, 50% relative humidity (RH) environment.
