Hjsil® 150

1 of 5 products in this brand

Hjsil® 150 is a high-purity hydrophilic fumed silica with a specific surface area of 150 m²/g. This white colloidal powder is widely used across various industries due to its controlled rheology and thixotropic properties. It serves multiple functions, including acting as an anti-sagging agent, thickener, reinforcing filler, and anti-caking agent. Hjsil® 150 is particularly useful in CASE (Coatings, Adhesives, Sealants, and Elastomers) applications where it helps to prevent sagging and improve viscosity. In composite materials, it enhances rheology and provides effective thickening, as well as anti-sagging and anti-caking benefits. This material is compatible with RTV (Room Temperature Vulcanizing) silicone and is ideal for formulations requiring high purity and white color. It is in powder form and can be used in both industrial and cosmetic applications.
