TiO2-pigmentsdiffer greatly depending on the type used in the final processing properties in the end product and the properties which they impart to the system to be pigmented.
TiO2-Pigment base properties such as brightness, undertone, and gloss and dispersibility play a role in pre-selection. Ultimately, however, it is not possible to get "the best" TiO2-Pigment to choose but jenes which is best suited for your application.
In the area of paint & coating applications, we measure in technical, highly concentratedTiO2-dispersion systems the electrostatic charge of the TiO2 Particle surfaces and the flocculation points, as well as the proportions of the additives adsorbed on the pigment surfaces. This results in numerous important findings about the present disperse TiO2-Pigment formulation.
-
Fast screening of the TiO2 types that are suitable for your application.
-
Screening of the entire stabilization process.
-
Accurate and reproducible setting of the "electro-steric" stabilization ratios.
-
Control of the stabilization process.
-
Lab-scale formulation optimization.
-
Easier transfer of the results to the pilot plant or production scale.
fillerswhich 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 for this task.
