Hjsil® 200

1 of 5 products in this brand
Hjsil® 200 is a high-purity hydrophilic fumed silica with a specific surface area of 200 m²/g. This white colloidal powder is designed for a wide range of applications, offering excellent anti-sagging, anti-caking, and thickening properties. It is particularly effective in RTV silicone adhesives and sealants, helping to improve transparency, hydrophilic properties, and anti-settling characteristics. Hjsil® 200 is compatible with RTV silicones and is ideal for formulations that require enhanced rheology control. Additionally, it is used in composite materials to provide anti-sagging, anti-caking, and thickening functions. This silica is available in bags and is commonly used in both industrial and adhesive applications, offering superior transparency and performance in various formulations.
