THSW-Acidic Series Colloidal Silica

THSW-Acidic Series Colloidal Silica distributed by Advent Silica is a series of ultra-high purity, acidic aqueous dispersions of colloidal silica with customizable SiO₂ content within the range of 10% to 30%. They are opalescent liquid, slightly more viscous than water. During the preparation, cationic ions like sodium (Na+) are removed. The acidic treatment replaces the sodium ions with hydrogen ions (H+), resulting in an acidic colloidal silica with a reduced pH value.

• They are suitable in catalyst supports, ceramic polishing, coatings, and other areas.
• THSW-Acidic Series Colloidal Silica have a shelf life of 12 months.
