Yingrui Hydrophobic Fumed Silica R-1208 is a modified, high-purity synthetic silicon dioxide designed for advanced performance in a wide array of industrial applications. It is a hydrophobic grade, meaning its originally hydrophilic surface has been chemically treated, typically with Polydimethylsiloxane (PDMS) as shown in the provided table, which ensures a strong resistance to moisture absorption and excellent dispersibility in organic and non-polar liquid systems. Characterized by a high surface area, generally ranging from 90 to 150 m²/g, R-1208 is primarily valued for its superior thickening, thixotropy control, and reinforcement capabilities. It is widely applied as a rheology modifier in adhesives and sealants—particularly silicone sealants, epoxy resins, vinyl resins, and gel coats—where it prevents sagging and sedimentation while boosting the material's mechanical strength and water resistance. Additionally, its robust hydrophobic nature makes it an effective flow-aid and anti-caking agent in powder systems like copier toners, improving powder flowability and charge characteristics. R-1208 is a versatile additive that enhances the stability, storage life, and application properties of multi-component formulations across the construction, electronics, and specialty chemical industries.hashtag#fumed silica#silica fumed#silicon dioxide#Email:rhea@sdyingrui.cn; michael@sdyingrui.cn#Whatsapp: +8613583505605;+8615154536501#https://lnkd.in/e4Kd-suw
