Introduction to Titanium Dioxide

Titanium dioxide (TiO₂) is a critical inorganic chemical known for its exceptional properties, including chemical stability, high whiteness, and strong tinting power. It is widely used as a white pigment in industries such as coatings, paper, plastics, and ceramics. The SR-2377 variant of titanium dioxide is specifically engineered to meet the demanding requirements of modern industrial applications, particularly in ink production.

Product Overview: SR-2377

The SR-2377 is a high-performance rutile titanium dioxide pigment treated with both inorganic (Zr, Al) and organic surface coatings. This advanced formulation ensures excellent gloss, medium durability, and superior dispersion properties. Designed for industrial-grade applications, SR-2377 is ideal for use in interior and exterior coatings, emulsion paints, powder coatings, inks, and plastics.

Key Features and Advantages

• Superior Whiteness: With a whiteness value of ≥97.0%, SR-2377 ensures vibrant, pure white finishes in coatings and inks.
• Excellent Gloss and Tinting Strength: The product delivers high gloss and a tinting strength of ≥180, enhancing the visual appeal of end products.
• Enhanced Durability: The Zr-Al surface treatment improves resistance to weathering and UV exposure, making it suitable for both indoor and outdoor applications.
• Good Dispersion: The organic treatment ensures uniform distribution in formulations, reducing agglomeration and improving product consistency.
• Chemical Stability: SR-2377 exhibits low solubility in water (≤0.5%) and maintains a pH range of 6.5–8.5, ensuring compatibility with diverse chemical systems.
