Filler properties and adantages in polishing and cleaning agents:
- loose structure, close and uniform particle size distribution
→ easy incorporation into water and O/W-emulsions, excellent dispersion properties (especially puriss products), quick and easy production, very low sedimentation speed, easily re-dispersible
- mineralogical composition (hardness)
→ stable and constant polishing efficiency
- extremely low residue of > 40 µm in puriss products
→ no unwanted scratching, high gloss finish
- availabble in different particle sizes
→ adjustable abrasivity
- synergetic effect with aluminum oxide
→ for badly contaminated but sensitive surfaces, very high gloss finish, expensive aluminum oxide can be reduced
- good rheological properties
→ thixotropic agent, control of rheology possible, reduction of expensive additives
- very low electrical conductivity, no buffer effect
→ good stability in aqueous formulas, no distrubing salts/electrolytes
- superior chemical resistance
→ high resistance to aggressive media such as acids and bases
- high purity
→ also suitable for food contact incl. drinking water as per FDA and BfR regulations
