Aluminum silicate AS881 is a synthetic silicate pure white, in a fluffy powder form with a very fine particle size.
It is mainly used in the coatings Industry as an extender of white pigment, especially for Titanium Dioxide (TiO2),
reducing cost of emulsion and decorative paints. Used as a thickener in paints and anti-misting additive in some printing inks.
-TiO2 extender for satin finish.
- Increased grade of whiteness and hiding power.
- Constant viscosity and pH value during storage.
- Abrasive resistance improvement.
- Gloss control.
- Anti-settling agent.
- Texture Control.
- Good resistance to weathering and scrubbing.
- Inks:
- Viscosity adjuster without affecting tack and yield value
- Reduced misting and strike-through.
- Reduced pigment settling in low viscosity inks.
