Superfine Micro-Nano Chemical Hydrophilic Fumed Silica 200 Price
Product Description
Fumed silica is the superfine micro-nano fine chemical product, which is divided into hydrophilic type and hydrophobic type in accordance with their different surface treatments. Its appearance is white powder. Native particle size ranges from 5nm to 40nm, with significant functions of thixotropy, reinforcing, thickening and filling. Therefore, it is widely used in the industries of rubber, sealant, plastic, resin, paint, printing ink, papermaking, medicine, cosmetics, food etc.

Application
Paints and Coatings
Fusil 200 fumed silica is mainly used in paints and coatings as thixotropic agent and anti-settling agent. It improves thixotropic and rheological properties of coatings and paint systems, retains original transparency of lacquers.
Furthermore, addition of fumed silica enhances hardening of coating film, adhesion to surfaces, as well as reduces deterioration rate of the coatings and fading of materials with transparent top coating. Besides, it helps to prevent run-off and sag of paints applied on vertical surfaces, thus ensuring top quality leveling. The fumed silica is used as a matting agent of lacquer systems, whereas the desired effect may be adjusted within wide ranges.
Adhesives and Sealants
Fusil 200 fumed silica is widely used in all kinds of adhesive and sealants industries, e.g. silicone sealants, PVC-plastisol sealant, polyacrylate sealant, expoxy adhesive, polyurethane adhesive, unsaturated polyester, polyurethane water-based adhesive, etc.
It is mainly used as additives for anti-sag, rheology control and anti-settling; also used as rheology control and reinforcing agents in sealants, and improves the storage stability and processability of adhesives and sealants.
RTV Silicone Sealant, HTV Silicone Rubber
Fusil 200 in RTV silicone sealant Fusil 200 provides thixotropy and reinforcement for RTV silicone sealants, while its shear-thinning property provides thickening and sag resistance at rest or low shear and thinning at high shear for easy application.
