  1. Above the bold line: TiO2 pigments. Below the bold line: non-TiO2 pigments, extenders or additives
  2. aThe bulk density was used to convert volume fraction to the added weight of pigment. While this introduces unknown variations due to differences in particle shape, size, and packing, the pigment-volume-concentration is a commonly used descriptor for paint films and was thus chosen in this study
