Product Description

Product Description

 

CAB-O-SIL® TS-720 is a medium surface area fumed silica treated with polydimethylsiloxane (PDMS) for exceptional performance in polar systems.
This advanced hydrophobic silica delivers superior thickening efficiency, sag resistance, and stable rheological control in demanding adhesive and coating applications.

PDMS surface treatment - Creates hydrophobic properties
Medium surface area - Optimized for polar systems
Exceptional sag resistance - Outperforms untreated silicas
Long-term stability - Maintains performance after aging

Typical Applications

CAB-O-SIL TS-720 fumed silica is used for rheology control in a wide variety of adhesives, composite and coatings applications
 

 

Epoxy Systems

• Superior sag resistance for vertical applications

• Excellent pigment suspension

• Long-term storage stability
   

Polyurethane Formulations

• Moisture-resistant - prevents premature curing

• Stable viscosity over time

• Improved film build
   

Vinyl Ester Resins

• More efficient than untreated silicas

• Better rheology control in high-polarity systems

• Enhanced gel coat performance

 

Epoxy Adhesives and Coatings:
In epoxy adhesives and coatings, CAB-O-SIL TS-720 fumed silica provides good thickening efficiency, sag resistance (or film build) and anti-settling of pigments and fillers. For appli cations requiring storage stability, CAB-O-SIL TS-720 fumed silica is recommended.

Polyurethane Adhesives and Coatings:
In polyurethane adhesives and coatings, CAB O-SIL TS-720 fumed silica provides the same efficient, stable rheology control as in epoxy systems. In addition, the hydrophobic surface of CAB-O-SIL TS-720 fumed silica introduces very little moisture into these systems preventing premature cross-linking of moisture cured sys tems.

Vinyl Ester Laminating Resins and Gel Coats:
While untreated silicas are effective thicken ers of unsaturated polyester resins, CAB-O-SIL TS-720 fumed silica is a more efficient, stable rheology control additive for higher polarity sys tems like vinyl ester laminating resins and gel coats
