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.
Ultra-low viscosity build – Provides strong anti-settling effect with almost no viscosity increase
Excellent hydrophobicity – Fully modified surface, no water marks on dried coating surface
Superior rheology control – Stable anti-sagging, improved leveling and scratch resistance
High-gloss compatibility – Does not reduce gloss in varnishes, maintains transparent finish
Enhanced powder flow – Improves flow and stability for easier transportation and application
