HS-830

HS-830 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 29% to 31% silica. 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. The small particle size allows it to easily penetrate the porous surfaces of concrete, thus increasing density and improving hardness as a densifier.

• It is widely used as a binder for the surface coat of the investment casting process, as well as refractory and ceramic applications.
• It is recommended for coatings applications for durability improvements.
• It is a customized modified formula that reduces the VOC emission and enhances the compatibility of traditional coatings.
• It enhances the rheological control, and exceptional cost-effectiveness.
• It offers excellent stability, great adhesion, durability, anti-settling-, and film-forming properties.
• HS-830 a has shelf life of 12 months.
