Frequently Asked Questions

R868 is a type of titanium dioxide (TiO2) pigment that has undergone specific surface treatments to improve its properties for various applications. Here's a breakdown of its characteristics:

1. Base Pigment: Rutile TiO2 is the primary component of R868. Rutile is one of the crystalline forms of titanium dioxide and is known for its high refractive index, which contributes to its excellent whiteness and opacity.

2. Organic Surface Treatment: R868 has been subjected to an organic surface treatment. This treatment involves the use of organic compounds that are adsorbed onto the surface of the pigment particles. Organic surface treatment can enhance dispersibility and compatibility with organic matrices (such as polymers or coatings) and may also provide improved stability and reduced agglomeration.

3. Inorganic Zirconium (Zr) Treatment: Additionally, R868 has undergone an inorganic surface treatment with zirconium (Zr). Inorganic treatments can further improve the pigment's performance and stability, making it suitable for a wider range of applications.

4. Aluminum Surface Coating: R868 is coated with aluminum. This aluminum surface coating provides several benefits, such as enhancing the pigment's durability, compatibility with specific systems, and improved color retention.

5. Whiteness: The combination of rutile TiO2 and the mentioned surface treatments gives R868 excellent whiteness, making it ideal for applications where high brightness and opacity are required.

6. High Flow: R868 has good flow properties. This means that it can disperse easily and evenly in various liquid and solid systems, ensuring a smooth and consistent application.

7. Good Gloss:The pigment's surface treatments and aluminum coating contribute to its ability to provide good gloss when incorporated into coatings, inks, and other formulations. This means that surfaces with R868-based products can have a shiny and reflective appearance.

R868's properties make it a versatile pigment choice for a range of applications, including paints, coatings, inks, plastics, and various other products that require high-performance pigmentation with enhanced color, whiteness, and durability.
