Product Description

Lithopone is a white Pigment, ZnSAndBarium sulfateMixture. By theZinc sulfateAndBarium sulfideDerived from the reaction solution, precipitation, filtration, drying and grinding , then calcined very badly burned red hot , pour into the water quench derived . Opacity secondary to titanium dioxide . No acid . Now with some lithoponeSurfactantBeenSurface Treatment. Lithopone also known as Zinc barium white , non-toxic white powder , insoluble in water , andAcidRole in decomposition of releaseHydrogen sulfide, and hydrogen sulfide andBaseDoes not work . ItHeatOf good , can improve the weather resistance , anti- algae , lower costs, and its excellent shielding power whiteness .
