Dongjia SR‑2400 Rutile Titanium Dioxide
1. Product Introduction
SR‑2400 is a rutile titanium dioxide pigment treated with silicon‑aluminum inorganic coating and organic surface modification, featuring high whiteness, excellent tint reducing power and superior weather resistance. SR‑2400+ is its upgraded version; through high‑temperature dense silica coating and optimized production process, it achieves further improved weather resistance and dispersion performance. It is specially developed for rigid PVC profiles, outdoor plastics, rubber and powder coating applications.
