Advent Silica THSW-Acidic Series
Colloidal Silica
Product Description
The THSW acidic series is a customizable series of acidic (2-4) aqueous dispersions of colloidal silica, with adjustable particle sizes ranging from 10 nm to 150 nm. Both the silica (SiOâ‚‚) content and particle size can be tailored to meet specific requirements. During preparation, cationic ions such as sodium (Naâº) are removed. The acidic treatment involves replacing the sodium ions with hydrogen ions (Hâº), resulting in acidic colloidal silica with a reduced value.

Safety & Handling
Review the corresponding Safety Data Sheet (SDS) before handling. Colloidal silica is a synthetic amorus silica dispersed in a stable form in water. Colloidal silica is not classified as harmful but mildly irritating. Protective gloves should always be used before handling and the use of protective glasses is strongly recommended. In case of skin or eye wash / rinse the area with plenty of water and seek professional medical help if needed.
