Key Applications of TiO2 R900
1. Paints and Coatings
In the world of paints and coatings, TiO2 R900 is prized for its ability to impart excellent coverage, durability, and UV resistance. Its high refractive index ensures that coatings are bright and vivid, providing long-lasting protection and aesthetic appeal to surfaces.
2. Plastics
For plastics, the incorporation of Titanium Dioxide R900 enhances product attributes by providing superior whiteness and preventing discoloration over time. It also plays a crucial role in improving the UV resistance of plastic products, extending their life span.
3. Inks
In the ink industry, TiO2 R900 is valued for its ability to produce bright, opaque colors. Its fine particle size allows for smooth printing and consistent color delivery, essential for high-quality printing outcomes.
4. Food Additives
Titanium Dioxide R900 also finds a place as a colorant in the food industry, where it is used to enhance the whiteness and brightness of products. However, it's important to note that the use of TiO2 in food applications is subject to regulatory approval and varies by region.
Technical Information of TiO2
Titanium Dioxide R900: This grade of TiO2 is optimized for applications requiring high levels of whiteness, brightness, and opacity. Its particle size and surface treatment are engineered to enhance dispersion in various media, making it highly effective in applications ranging from high-end coatings to consumer goods. The sulfate process used in its production allows for the customization of particle size to fit specific application needs.
KA100: Represents a category of potassium feldspar minerals, which are valued for their chemical resistance, durability, and thermal stability.
