Silica-based sols |
| abstract |
An aqueous sol containing silica-based particles is used as a drainage and retention aid in the production of paper. The sol has a specific surface area of at least 90 m2/g aqueous sol and an S-value within the range of from 10 to 45% or contains silica-based particles having a specific surface area of less than 1000 m2/g SiO2. |
