THZ-Neutral Series

THZ-Neutral Series distributed by Advent Silica act as binder and surface modifier. It is a series of ultra-high purity, near-neutral colloidal silica with customizable SiO<sub>2</sub> content within the range of 10 to 30%. They are not stabilized by a counterion like other grades, which makes it a versatile agent in both alkaline or acidic environments. They are used in preparing ceramic slurries in investment casting process and coatings application. THZ-Neutral Series have a shelf life of 12 months.

HS-40 (Alkali)

HS-40 (Alkali) distributed by Advent Silica acts as a binder and surface modifier. It is an alkaline, versatile, small particle sized, aqueous dispersion of colloidal silica with 40% silica. The average particle size can be fine-tuned between 10 and 20 nm. It is a sodium stabilized, translucent liquid, slightly more viscous than water. It is produced through the hydrolysis of very fine silica powder, a technique that yields colloidal silica characterized by its lower level of impurities (metal ions), more uniform and even particle distribution. <br> <ul style="padding-left: 40px;"> <li> It is recommended for coatings applications for durability improvements. </li> <li> It is a customized modified formula that reduces the VOC emission and enhances the compatibility of traditional coatings. </li> <li> It offers excellent stability, great adhesion, durability, anti-settling-, and film-forming properties. </li> <li> It has exceptional versatility and cost-effectiveness. </li> <li> HS-40 (Alkali) a has shelf life of 12 months. </li></ul>
