Introduction to Zr.Al Coated Rutile Grade (ZL-928R)

Zr.Al Coated Rutile Grade (ZL-928R) is a premium titanium dioxide (TiO₂) pigment with a rutile crystal structure, enhanced by surface coatings of zirconium (Zr) and aluminum (Al). This coating provides the pigment with superior properties, including enhanced dispersion, increased opacity, and improved weathering resistance. It is widely used in coatings, plastics, and other industrial applications, offering excellent color performance and long-lasting durability.

Chemical Composition and Structure

The Zr.Al Coated Rutile Grade (ZL-928R) is produced by coating rutile titanium dioxide with a layer of zirconium oxide (ZrO₂) and aluminum oxide (Al₂O₃). The combination of rutile crystal structure and the zirconium-aluminum coating results in a high-performance pigment that exhibits superior hiding power and enhanced weatherability.
