Light Stability Titanium Dioxide for Topcoats/Processing/Powder Coatings/Electrodeposition Primers

If the product requires high weather resistance, opacity and long-term whiteness stability, rutile is usually the preferred choice. If the product's primary focus is on whiteness, dispersibility and cost control, anatase may be considered depending on the specific application.

Not necessarily. Once the loading reaches a certain level, further increases in titanium dioxide do not necessarily result in a proportional increase in whiteness; instead, they may lead to difficulties in dispersion, changes in viscosity, reduced processability and increased costs. It is therefore more important to select the appropriate titanium dioxide grade and a reasonable loading level.

Yes. In systems such as PVC and plastics, titanium dioxide can generally be used in combination with calcium carbonate. Calcium carbonate primarily serves to act as a filler, enhance rigidity and optimise costs, whilst titanium dioxide is mainly responsible for whiteness, opacity and colouring effects. A sensible combination can optimise the overall formulation cost whilst ensuring the product's appearance.

Different brands and grades vary in terms of crystal structure, particle size, surface treatment, TiO2 content, whiteness, blue shift and dispersibility. Consequently, even when added in the same proportions, the colour of the final product may differ.

Yes. We can assist you in selecting a product based on the PVC resin grade you provide,as well as the product type, processing method, processing temperature, equipment type, current formulation and stabiliser dosage.
