CAB-O-SIL TS-720 treated fumed silica is a highpurity silica which has been treated with a dimethyl silicone fluid. The treatment replaces many of the surface hydroxyl groups on the fumed silica with a polydimethyl-siloxane polymer. This treatment makes the silica extremely hydrophobic.
The unique properties of TS-720 treated fumed silica offer special benefits in many applications
- The low moisture content of TS-720 (typically 0.2 wt. %) makes it usable without expensive drying when incorporated in moisture-sensitive systems
- TS-720 is an excellent thixotrope for coatings, providing sag resistance, anti-settling, rheology control, and superior water resistance.
- TS-720 is a very efficient thixotrope for epoxy resins. It offers a stable sag resistance, even in high-temperature cure systems, without loss of other proeprties such as cure rate, extrusion rate, or lap shear tensile strength.
