Rutile Grade Titanium Dioxide 9000 2377 CAS 13463-67-7
SR-9000 is a high-performance rutile titanium dioxide (TiO₂) pigment manufactured by DOGUIDE Group, designed for advanced industrial applications. This product undergoes specialized zirconium (Zr) and aluminum (Al) inorganic surface treatment, combined with organic surface modification, delivering exceptional whiteness, high tinting strength, and superior water dispersibility. It is engineered to meet the stringent performance requirements of high-end coatings, inks, and automotive refinish systems, making it a versatile solution for demanding industrial environments.
2. Key Performance Characteristics
SR-9000 stands out in the market due to its optimized surface treatment and core material properties:
• Superior Optical Performance: The product achieves a dry powder whiteness (WH) of ≥97.5% and an L-value of ≥98.0, ensuring excellent brightness and color consistency in end products. Its tint reducing power (≥180, compared to standard) delivers outstanding hiding power and color saturation, critical for high-gloss and decorative coatings.
• Enhanced Durability: The Zr/Al inorganic coating provides excellent weather resistance, chemical stability, and anti-chalking properties, extending the service life of coatings in outdoor and harsh environments. The organic surface treatment further improves dispersibility in both aqueous and solvent-based systems, reducing processing time and improving film uniformity.
• High Purity & Low Impurities: With a TiO₂ mass fraction of ≥93.0% and rutile content of ≥97.0%, SR-9000 maintains minimal impurities (water-soluble content ≤0.5%, residue ≤0.01%), ensuring consistent performance and compatibility with various formulation systems.
