High-Gloss Titanium Dioxide Powder: Properties, Applications & Benefits

High-gloss, highly dispersed titanium dioxide powder is a specialty powder in the titanium dioxide material system designed for high-end applications. Its core advantages lie in three aspects: excellent gloss performance, superior dispersion properties, and stable durability.

These characteristics make it particularly suitable for glossy surface coatings that require high surface smoothness and performance stability, serving the high-quality manufacturing sector that demands higher standards for material performance, and meeting the current demand for refined materials in industrial upgrading.

The high gloss characteristic is attributed to precise particle size control and advanced preparation processes. Currently mainstream chloride or optimized sulfuric acid processes, through strict control of key parameters such as reaction temperature and nucleating agent dosage, ensure a concentrated and uniform particle size distribution, effectively reducing the presence of oversized particles.

This results in a smoother and more even surface after the coating dries, with more uniform light reflection, thus exhibiting excellent gloss. Furthermore, a refined impurity removal process and unique surface treatment technology give the powder higher whiteness and a refreshing blue undertone, further enhancing the visual effect of the coating and meeting the appearance requirements of high-quality applications.

High dispersibility is a core technological highlight of this product and a crucial prerequisite for ensuring uniform coating performance. Through particle size control, deagglomeration treatment, and surface modification, the agglomeration of powder particles is significantly suppressed. In practical applications, it can quickly and uniformly disperse in coating systems, fully integrating with resins and other components without complex pretreatment processes.

According to GB/T 19591-2023 "Nano Titanium Dioxide" standard, the agglomeration index of high-quality products is typically controlled within a certain range, and Zeta potential testing also indicates good dispersion stability. This not only improves production efficiency but also avoids coating defects caused by uneven dispersion, ensuring a smooth and uniform final coating surface.

Regarding durability, this product utilizes a high-purity rutile crystal structure combined with zirconium oxide or alumina inorganic coating treatment, exhibiting excellent lightfastness, anti-chalking, and weather resistance, making it suitable for outdoor and harsher environments.

Testing shows stable gloss retention and anti-chalking performance; even after prolonged exposure to sunlight, the coating maintains good gloss and color stability. Meanwhile, it also possesses good chemical corrosion resistance, resisting the erosion of common acid and alkali media, extending the service life of the coating, reducing later maintenance costs, and meeting the durability requirements of high-quality products.

In terms of applications, this powder is mainly suitable for glossy surface coatings, such as industrial coatings, automotive paints, and high-end architectural coatings. In automotive paints, it can be used in OEM original paints and repair paints, relying on high gloss and high dispersibility to present a delicate and smooth paint surface effect while ensuring the weather resistance of the paint film.

In high-end architectural coatings, it is suitable for door and window paints, coil coatings, etc., meeting the gloss requirements of decorative effects while resisting the impact of outdoor environments. In addition, it can also play a role in high-end printing inks and plastic coloring, providing support for improving the appearance quality of products.

Currently, the production and quality control of this type of product has established a relatively mature system. In accordance with relevant national standards such as GB/T 19591-2023, the company conducts strict testing on indicators such as powder purity, particle size distribution, dispersibility, and weather resistance to ensure stable and controllable product performance.

With the promotion of the chlorination process and the continuous upgrading of domestic technology, the performance of domestic high-gloss and high-dispersion titanium dioxide powder is gradually approaching the international level, which can meet the diversified material needs of high-end manufacturing fields, and also provides strong material support for the development of coatings, plastics and other industries towards refinement and high-end.
