Tokuyama REOLOSIL QS-09 Hydrophilic Fumed Silica

Tokuyama REOLOSIL QS-09 is a hydrophilic fumed silica imported from Japan. It features ultra-low specific surface area and high fluidity, with precise rheology control and efficient reinforcement, suitable for coatings, polishing, silicone rubber and other fields.

Features Of Tokuyama REOLOSIL QS-09 Hydrophilic Fumed Silica

  1. Ultra-low specific surface area – uniform particle size, suitable for low-viscosity formulations without affecting fluidity

  2. Efficient rheology control – precisely adjust liquid thixotropy, prevent sagging and sedimentation, improve construction convenience

  3. Excellent reinforcement – enhance mechanical strength of silicone rubber and sealants, improve durability and adhesion

  4. Easy dispersion and processing – fluffy white powder, no agglomeration after addition, reduce processing difficulty

  5. Multi-scenario adaptation – anti-caking and flow aid functions, suitable for polishing and other special fields

Typical Applications Of Tokuyama REOLOSIL QS-09 Hydrophilic Fumed Silica

  1. Coating systems – water-based/UV coatings, leather finishing, thickening and anti-sagging, improve stability and transparency

  2. Polishing and grinding – used as abrasive particles for polishes and abrasives, enhance grinding effect and surface finish

  3. Silicone rubber products – reinforcement for HCR-RTV-2K silicone rubber, improve toughness and service life

  4. Sealants/adhesives – thickening and thixotropy, prevent filler sedimentation, enhance bonding strength

  5. Powder products – anti-caking and flow aid, improve storage and processing performance
