Various TiO2 pigments differ clearly in the final processing properties in the end product and the properties they bring into the pigmented system.
TiO2 pigment basic properties such as brightness, undertone and gloss play a role in the pre-selection. Ultimately, however, it is not possible to choose "the best" TiO2 pigment, but rather the one that is best suited for your application.
In the field of paints & lacquer applications, we measure the electrostatic charge of the TiO2 particle surfaces and the flocculation points, the proportions of the adsorbed surface-affine additives, in technical, highly concentrated TiO2 dispersion systems. This results in numerous important findings about the present disperse TiO2 pigment formulation.
Fast screening of the TiO2 pigment grades that are suitable for your application.
Screening the entire stabilization process.
Precise and reproducible setting of the "electro-steric" stabilization ratio.
Control of the whole stabilization process.
Optimization of the formulation on a laboratory scale.
Reliable transfer of the results to the pilot plant or production scale.
Fillers that are used in the recipe also have different surface properties, especially when they are functionalized. Such filler systems must match the surface properties of the TiO2 pigment used in order to produce excellent product properties. The appropriate pH value windows are determined in the same way.
