Product highlights: CAB-O-SIL TS-382 fumed silica is a medium surface area fumed silica which has been surface modified with octyltrimethoxysilane. The treatment replaces some of the hydroxyls on the surface of the silica, resulting in increased hydrophobicity and very different performance than untreated silica. CAB-O-SIL TS-382 fumed silica is characterized by: - High purity
- Aggregated structure
- Submicron particle size
- Low bulk density
- Hydrophobic surface chemistry
CAB-O-SIL TS-382 fumed silica provides the following performance advantages in medium to high polarity systems: - Sag resistance or high film build
- Anti-settling of pigments and fillers
- Shear-thinning rheological behavior
- Stable rheological performance over time
Key application: CAB-O-SIL TS-382 fumed silica provides stable rheology control in medium to high polarity coatings formulations such as epoxies. CAB-O-SIL TS-382 fumed silica has a better balance of inter-coat adhesion and sag resistance than Cabot’s CAB-O-SIL TS-720 fumed silica, making it a better choice for use in multi-coat systems. CAB-O-SIL TS-382 fumed silica provides a good balance between sag resistance and flow and leveling, allowing formulators to control film thickness and appearance.Information provided by Cabot Corporation |
