AERODISP W 630 Aqueous dispersion of hydrophilic fumed aluminium oxide 1344-28-1 Degussa-Silanes Filler >> Aluminum oxide INKS >> Digital inks (eg. Ink jet) AERODISP® W 630 is a dispersion with a high solid content and slightly acidic pH value. The cationic nature of this alumina based dispersion is well suited for fixing dyes. This combined with fast ink absorption aids in development of high quality inkjet coatings. It possesses positively charged solid particles, high solid content (approx. 30 wt. %), nano-sized primary particles, superior rheological behavior, easy to handle. It is used in inkjet coatings for film and paper, enables the development of formulations at high solids content, creates high gloss microporous coatings with transparency, shortens ink drying times ("Instant Dry"), optimizes print resolution for photo quality applications, provides excellent colorant fixation (dyes and pigment based inks), enhances rub and smudge resistance, improves waterfastness.
