titanium dioxide suitable for exterior wall latex paint

The role of titanium dioxide in latex paint
Titanium dioxide in latex paint mainly plays the role of increasing hiding power and improving whiteness. By scattering light, titanium dioxide provides an excellent white effect, making latex paint more decorative and weather-resistant. In addition, titanium dioxide can also enhance the UV resistance and durability of latex paint.

These parameters indicate that the titanium dioxide has good dispersibility and stability and is suitable for the preparation of exterior wall latex paint.

In addition, the application effects of titanium dioxide in exterior wall latex paint are as follows:

‌Hiding Power‌: Titanium dioxide can significantly improve the hiding power of a coating, allowing the coating to better cover surface imperfections on the substrate.
‌Gloss‌: By adding an appropriate amount of titanium dioxide, the glossiness of the paint can be improved, making the painted surface smoother and brighter.
‌Weather resistance‌: Titanium dioxide has good weather resistance and can extend the service life of the coating, especially performing well in outdoor environments.
‌Chemical stability‌: Titanium dioxide exhibits excellent chemical stability in coatings and can resist erosion from various environmental factors.

The parameters of titanium dioxide suitable for exterior latex paint mainly include particle size, dispersibility and purity. ‌

‌Particle size‌: The particle size distribution of titanium dioxide has an important influence on its performance. Reasonable particle size distribution can improve the hiding power and dispersibility of the paint. Studies have shown that when the particle size of titanium dioxide is controlled within a certain range, the physical and chemical properties of exterior wall paints are better, the hiding power is stronger, and the solvent resistance and weathering resistance are better. ‌
‌Dispersibility‌: Good dispersibility can ensure that titanium dioxide is evenly distributed in the paint, thereby improving the gloss and adhesion of the paint. The better the dispersibility of titanium dioxide, the better the uniformity and texture of the paint. ‌

Purity‌: High-purity titanium dioxide can provide better hiding power and stability. The higher the purity of titanium dioxide, the better its hiding power and weather resistance.
