CAB-O-SIL@ TS-720 FU M ED SILICA
Product highlights
CAB-O-SIL fS-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-SILTS-720 fumed silica is characterized by
r High purity
t Aggregated structure
t Submicron particle size
o Low bulk density
r Hydrophobic surface chemistry
Key applications
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:
r Thickeningefficiency
r Sag resistance or high film build
i Anti-settling of pigments and fillers
I Shear-thinningrheologicalbehavior
o Stable rheological performance over time
