Product highlights
CAB-O-SIL TS-720 fumed silica is a medium surface area fumed silica which has been surface treated with polydimethylsiloxane (PDMS).
This surface treatment results in a hydrophobic silica with a very different performance than untreated silica.
CAB-O-SIL TS-720 fumed silica is characterized by:
High purity
Aggregated structure
Submicron particle size
Low bulk density
Hydrophobic surface chemistry
Providing excellent thickening, anti-settling
Rheological control properties
Enhancing the stability and thixotropy of products
Offering good hydrophobicity and dispersibility
CAB-O-SIL TS-720 fumed silica is used for rheology control in a wide variety of adhesives, composite and coatings applications.
This product provides the following performance advantages in medium to high polarity systems:
Thickening efficiency
Sag resistance or high film build
Anti-settling of pigments and fillers
Shear-thinning rheological behavior
Stablerheological performance over time
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.
Polyurethane adhesives and coatings
In polyurethane adhesives and coatings, cab-o-sil ts-720 fumed silica provides the same efficient, stablerheology 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, retarding premature cross-linking of moisture cured systems.
Vinyl ester laminating resins and gel coats
While untreated silicas are effective thickeners of unsaturated polyester resins, cab-o-sil ts-720 fumed silica is a more efficient, stablerheology control additive for higher polarity systems like vinyl ester laminating resins and gel coats.
