ALATAI™ R-577 Rutile Titanium Dioxide Pigment for Coatings Applications

Product Overview

ALATAI™ R-577 rutile titanium dioxide pigment for coatings is a sulphate-process general-purpose TiO₂ grade designed to deliver balanced optical performance, stable processing behavior, and cost-efficient formulation flexibility. It is engineered for manufacturers requiring consistent whiteness, strong hiding power, and reliable dispersion across large-scale industrial production.

R-577 is developed with controlled particle size distribution and advanced surface treatment technology using zirconia (ZrO₂), alumina (Al₂O₃), and organic modification. This structure ensures stable performance in coatings, inks, plastics, and masterbatch applications.

Product Positioning and Value

R-577 is positioned as a cost-effective alternative to standard rutile titanium dioxide grades such as R996. It focuses on practical performance balance rather than premium specialization, making it suitable for mass production environments where stability and cost control are equally important.

The product delivers three core advantages: stable whiteness output, reliable dispersion behavior, and optimized production cost efficiency. These characteristics allow formulators to maintain consistent product quality while improving economic efficiency.
