The work is focused on modifying and proposing a more effective procedure for evaluating the quality of titanium dioxide, making it possible to obtain reliable and scalable results at an industrial level on the performance of the pigment in the final product. For this purpose, the usual procedure will be modified and its parameters will be adapted according to the working conditions of the Production Plant. The information in the technical data sheet of a titanium dioxide sample provides important information about its manufacture, via chloride and sulfate, which will help us predict the results of the evaluation and will be verified in the laboratory. Titanium dioxide sample evaluations will be given, during and after the manufacture of a polyurethane-based paint at the laboratory level. The dispersion time is the most relevant parameter in the choice of a titanium dioxide sample to be used in production, being a maximum of 10 minutes. The ratio of the diameter of the container to the high shear driver is 3 to 1; and the weight ratio between resin and titanium dioxide is 4 to 1, both adjustments being proportional to the conditions that are used at an industrial level. Using the modified procedure, seven samples of titanium dioxide from different suppliers have been evaluated, and among them only R-1931 achieved the required fineness in the optimal time established by the laboratory and had no problems at the industrial level.
