THN-Ammonium Series

THN-Ammonium Series distributed by Advent Silica acts as a binder and surface modifier. They are an alkaline, aqueous dispersion of colloidal silica within the range of 10 to 30%. They are an opalescent liquid, slightly more viscous than water. They are stabilized by ammonium (NH₄+) ions, as opposed to sodium (Na+) ions, make them suitable for applications where sodium ions are sought to be avoided. During the preparation process, amino groups are introduced to the silica surface, enabling interactions with amines, and forming hydrogen bonds. This stabilizes the dispersion in the aqueous phase and prevents agglomeration.

• It is a specialized series where the particle size and silica content can be tailor according to the specific needs of the application.
• They are designed for scenarios where minimizing the introduction of sodium ions is preferred.
• They are recommended for coatings, petrochemical catalyst supports (e.g., zeolites), and concrete, among others where avoiding sodium-stabilizing ions could prove advantageous.
• They offer excellent stability, great adhesion, durability, and film-forming properties.
• They are a customized modified formula that reduces the VOC emission and enhances the compatibility of traditional coatings.
• They enhance rheological control and improved anti-settling properties.
• THN-Ammonium Series have a shelf life of 12 months.
