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.
