Hoffmann Mineral: Beneficios de sus cargas en pinturas y barnices

Filler properties				Effect 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 (<>				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
