TiO2 in industrial coating

When discuss on titanium dioxide for industrial coatings, especially in the paint formulation design, in addition to selecting the appropriate TiO2 grade, another key issue is how to determine the optimal use of TiO2. This depends on the need for coating opacity, but other factors are also key important such as PVC, wetting and dispersing, film thickness, solids content, and the presence of other coloring pigments.

For room temperature curing solvent-based white coatings, we can select the titanium dioxide content, from 350Kg/1000L for high-quality coatings to 240kg/1000L for economical coatings, when the PVC is 17.5% or in the ratio of 0.75:1. The solid dosage is 70%~50%; for decorative latex paint, when PVC, CPVC, we can also reduce the amount of TiO2 with the increase of dry hiding power.

In some economical coating formulations, we can reduce the amount of TiO2 to 20kg/1000L. In high-rise building exterior wall coatings, we can reduce the content of titanium dioxide to a certain proportion, and the adhesion of the coating film can also be increased.
