Hydrophobic Fumed Silica LC-HFS508

LC-HFS508 is a hydrophobic fumed silica surface treated with HMDS (hexamethyldisilazane) on a hydrophilic fumed silica with a specific surface area of 400. It is mainly used in powder materials, powder coatings, carbon powder, defoamers, and high replenishment materials.

Features & Benefits of Hydrophobic Fumed Silica LC-HFS508

  • HTV silicone rubber and liquid silicone rubber reinforcing agents have higher transparency, ultra-high hydrophobicity, and stable thixotropy.

  • Prevent sedimentation, sagging, and thixotropy in coatings and inks

  • Endow defoamers with excellent defoaming ability and prolong the defoaming time

  • Improve the free flow, uniformity, and stability of carbon powder

  • Improve the dispersibility of mixed powder materials

  • Improve the anti-corrosion and temperature resistance of adhesives and sealants

  • Make the insulation board and insulation coating have good insulation performance


Applications of Hydrophobic Fumed Silica LC-HFS508

  • Reinforcing agents for HTV silicone rubber and liquid silicone rubber

  • Powder coatings and powder materials

  • Adhesives and sealants

  • defoamer

  • thermal insulation material
