Dongjia SR-240 Rutile Titanium Dioxide
1. Product Introduction
SR-240 is a rutile titanium dioxide pigment treated with inorganic aluminum coating and organic surface modification. It features excellent gloss, strong hiding power, anti-chalking performance and outstanding dispersion in plastics and rubber systems. SR-240+ is an upgraded version of SR-240, with higher bulk density, enabling higher concentration masterbatch production without additional dispersing agents.
