Hydrophilic Fumed Silica CAS 112945-52-5
Sinochem is a major Hydrophilic Fumed Silica supplier. Meanwhile, our firm staffs a group of experts devoted to your development of China Hydrophilic Fumed Silica.
Hydrophilic fumed silica is a high-purity thickening and reinforcing agent. Produced by flame hydrolysis, its nano-sized particles form a 3D network in liquid systems, providing excellent rheology control, anti-settling, and thixotropy for a wide range of applications like coatings, adhesives, and sealants.
- Rheology and thixotropy modifiers
- Anti-settling agents, thickeners, and anti-sagging agents
- Improve free flow and prevent caking
- Reinforcement agents for silicone rubber
