Introduction to ZL-950C Titanium Dioxide

ZL-950C is a Zirconium and Aluminum surface-treated rutile grade titanium dioxide (TiO₂), designed for high-performance applications requiring exceptional brightness, dispersibility, and weather resistance. Produced via the sulfate process, this pigment demonstrates outstanding optical properties and surface activity, making it suitable for coatings, plastics, inks, and other demanding industrial applications.

Chemical Composition and Structure

ZL-950C consists of fine particles of rutile-type titanium dioxide, which are surface-treated with zirconium (ZrO₂) and aluminum oxide (Al₂O₃) to enhance pigment stability, improve dispersibility, and reduce photoreactivity. This coating acts as a barrier layer that minimizes chalking and enhances resistance to UV degradation.
