Benefits in paint and varnish systems

loose structure,
small particle size

quick and good incorporation,
excellent dispersibility (especially puriss products),
very little tendency towards sedimentation,
no hard sediment,
favorable rheological properties,
matting effect,
rapid drying,
breathability,
water vapor permeability,
good corrosion protection,
good pigment dispersion (spacer effect),
reduced wet-edge strength,
good sanding,
excellent stone impact resistance,
good mechanical properties (crack bridging)

non-ground filler,
low grit content

low abrasivity

very low electrical conductivity (< 100 µS/cm)

no disturbing electrolytes,
good bath stability in electrophoretic applications

no buffer effect

good stability in water based varnish systems

mineralogical composition (hardness)

scratch resistance,
abrasion resistance

chemically inert

weather and chemical resistance, especially acids

similar refraction index as binder

very good transparency
(for clear lacquer systems)

surface treatment possible

good bond filler to polymer
