Characteristics:
Fumed Silica TP-20 is a fumed hydrophobic silica treatedwith polydimethylsiloxane, with very good thickening properties.
Properties:
Highly efficient effect in the thickening and thixotropyof complex polar liquids.
Improves the water resistance of moisture-sensitiveformulations.
Improvement of the anti-settling behavior of pigments andanti-sagging behavior in epoxy coatings.
Used as surface additive for toner particles to increasecharge and improve flow-ability.
