Cabot CAB‑O‑SIL TS‑530 Hydrophobic Fumed Silica

Cabot CAB‑O‑SIL TS‑530 is a hydrophobic fumed silica modified with HMDS, specially designed for high‑solid coatings, varnishes and powder coatings. It delivers excellent anti‑settling, rheology control and hydrophobicity with minimal viscosity increase, ensuring high gloss and water‑mark resistance.

Features Of Cabot CAB‑O‑SIL TS‑530 Hydrophobic Fumed Silica

  1. Ultra-low viscosity build – Provides strong anti-settling effect with almost no viscosity increase

  2. Excellent hydrophobicity – Fully modified surface, no water marks on dried coating surface

  3. Superior rheology control – Stable anti-sagging, improved leveling and scratch resistance

  4. High-gloss compatibility – Does not reduce gloss in varnishes, maintains transparent finish

  5. Enhanced powder flow – Improves flow and stability for easier transportation and application

Typical Applications Of Cabot CAB‑O‑SIL TS‑530 Hydrophobic Fumed Silica

  1. High-solid industrial coatings and varnishes

  2. Powder coating systems

  3. UV curable coatings

  4. Anti-corrosion and metal flake orientation coatings

  5. Various liquid coatings requiring low viscosity and high hydrophobicity
