Titanium Dioxide (Rutile) — PW6 / CAS 13463-67-7 / ASTM D476 Type II

Description

1. Product Overview

Titanium Dioxide (Rutile) — PW6 (CAS 13463-67-7, ASTM D476 Type II) is a high-performance inorganic pigment widely used across coatings, plastics, inks, and construction materials. It delivers superior opacity, brightness, and UV resistance, making it a critical functional additive for high-durability industrial formulations.

Its rutile crystal structure ensures enhanced weatherability and long-term color stability compared to anatase grades, providing manufacturers with improved lifecycle performance and reduced rework costs. In global supply chains, PW6-grade TiO₂ is strategically important due to its role in enabling premium surface finish, product differentiation, and long-term material protection under harsh environmental conditions.
