Using Composite TiO2 Pigments to Reduce The Use of Coloured Pigments Hence Reducing Cost And Carbon Footprint

Coloured pigments are obviously vital to imparting the apparent colour to coatings materials. However, in almost all cases, variations in the opacifying power of this largely absorptive materials mean that significant amounts of Titanium Dioxide is required in the formulation in order confer the appropriate level of opacity.

This necessary amount of TiO₂ has the detrimental effect of scattering white light at the film surface and reducing the Chroma and strength of the coloured pigmen.

New developments in opacifying composite pigment technology allow the use of significantly less TiO2 in such coloured systems whilst maintaining opacity. This provides a great opportunity to reformulate coatings using less coloured pigment hence reducing costs and carbon footprint.
