Frequently Asked Questions


R-216 is a specific type of rutile titanium dioxide (TiO2) pigment that is produced using the sulfate process. TiO2 is a widely used white pigment in various industries, including paints, coatings, plastics, inks, and cosmetics. It is known for its exceptional opacity, brightness, and high refractive index, which contributes to its ability to scatter and reflect light effectively.

The sulfate process is one of the methods used to produce titanium dioxide. In this process, titanium dioxide is obtained from naturally occurring titanium ores, such as ilmenite or rutile, by reacting them with sulfuric acid. This process yields a pigment with a rutile crystal structure, which has superior performance compared to the anatase form.

R-216, as a rutile titanium dioxide pigment, possesses several key characteristics:

1. White Powder: R-216 appears as a fine, white powder, which is typical of titanium dioxide pigments.

2. High Gloss: The pigment provides a high level of gloss or shine when used in various applications like coatings, paints, and plastics.

3. Opacity: It has excellent opacity, meaning it can effectively cover or hide the substrate it is applied to, even at low concentrations.

4. UV Stability: Rutile titanium dioxide exhibits good UV stability, making it suitable for outdoor applications where resistance to UV degradation is crucial.

5. Chemical Inertness: Titanium dioxide is chemically inert, which means it is not easily reactive with other substances, ensuring stability in the final product.
