Titanium dioxide (TiO₂) is by far the most suited white pigment to obtain whiteness and hiding power in coatings, inks and plastics. This is because it has an extremely high refractive index and it does not absorb visible light. TiO₂ is also readily available as particles with the right size (d ≈ 280 nm) and the right shape (more or less spherical) as well as with a variety of post-treatments.

However, the pigment is expensive, especially when the volume prices of systems are used. And, there always remains a need to develop a full-proof strategy to obtain the best results in terms of cost/performance ratio, scattering efficiency, dispersion… while using it in coating formulations. Are you searching for the same?

Explore the detailed knowledge of TiO₂ pigment, its scattering efficiency, optimization, selection, etc. to achieve the best possible white color strength and hiding power in your formulations.

Le lithopone est produit par coprécipitation de sulfure de baryum et de sulfate de zinc, le plus souvent en proportions équimolaires, puis grillage de la pulpe résultante⁴.

Lithopone: an alternative to titanium dioxide

Lithopone can also be used as raw material of putty to fill gaps; Adding 20% lithopone to the concrete to make artificial quartz without harming its light resistance and solidification; It can improve the impact resistance and electrical performance when used in fire safety polyester chemicals; These are the raw materials of audio vinyl records used for turbojet engine dye and thermal insulation coating and insulating layer.
