Rutile Titanium Dioxide R218
High Whiteness & Easy Dispersion TiO₂ for Plastics and General Coatings
Product Overview
R218 is a versatile rutile titanium dioxide (TiO₂) pigment designed for plastics and general-purpose coating applications.
It offers an excellent balance of high whiteness, good opacity, and easy dispersion, making it a cost-effective choice for manufacturers who require stable processing performance and consistent visual quality.
Thanks to its optimized particle size distribution and surface treatment, R218 performs reliably in both plastic processing and coating formulations.

FAQ – R218 Titanium Dioxide
Q1: Is R218 suitable for outdoor applications?
A: R218 is mainly recommended for indoor plastics and coatings. For long-term outdoor exposure, we suggest a higher weather-resistance grade such as R996.
Q2: Can R218 be used in plastic masterbatch production?
A: Yes. R218 offers excellent dispersion and is widely used in both white and color masterbatch systems.
Q3: Is R218 compatible with water-based coatings?
A: Yes, it performs well in both solvent-based and water-based coating systems.
Q4: What is the recommended storage condition?
A: Store in a dry, cool environment and keep the packaging sealed to prevent moisture absorption.
