Abstract
This study optimized the Precipitated Calcium Carbonate (PCC) and lithopone mixture (50:50) as substitution pigments of titanium dioxide (TiO2) in matt-type water-based paint. Matt-type water-based paint has been made in two steps; (1) mill base paste preparation and (2) water-based paint production (layout process). Pigment characterization showed that PCC/lithopone mixture produced a white solid of 95.57%, crystallinity degree of 91.5%, and a diameter small size particle of 198.29 nm. Application of PCC/lithopone mixture as pigment into matttype water-based paints has resulted in good dispersibility and hiding power while exhibiting the same whiteness quality as TiO2 and glossy better than TiO2. Keywords: PCC; Lithopone; TiO2; Pigment
