Titanium Dioxide (TiO₂) is a critical inorganic chemical with widespread applications in coatings, papermaking, plastics, ceramics, and more. Among its variants, SR-2377 stands out as a high-performance rutile titanium dioxide pigment engineered for superior optical and physical properties. This article provides a comprehensive overview of SR-2377, its technical specifications, applications, and the company behind it, Hebei Caiqing New Material Technology Co., Ltd.

Product Overview: SR-2377 Rutile Titanium Dioxide

SR-2377 is a high-purity rutile titanium dioxide pigment that undergoes advanced surface treatment with zirconium (Zr) and aluminum (Al) inorganic compounds, combined with organic modifications. This dual treatment enhances its performance in various industrial applications. The product is designed to deliver excellent gloss, medium durability, and optimal dispersion, making it ideal for demanding environments such as coatings, inks, and plastics.

According to Hebei Caiqing New Material Technology Co., Ltd., SR-2377 is tailored for interior and exterior coatings, emulsion paints, powder coatings, inks, primers, rubber, masterbatches, and plastics. Its high whiteness (≥97.0%) and excellent tinting strength (≥180) ensure vibrant, long-lasting coloration. Additionally, its low oil absorption (16-20 g/100g) and high specific resistance (≥8000 Ω·cm) make it a reliable choice for industrial-grade applications.

Key Advantages of SR-2377

SR-2377 offers several distinct advantages over conventional titanium dioxide pigments:

• Superior Gloss and Whiteness: The high whiteness (≥97.0%) and L value (≥98.0) ensure a bright, uniform finish in coatings and inks.
• Excellent Dispersion: The inorganic and organic surface treatments enhance its ability to disperse evenly in formulations, reducing clumping and improving stability.
• High Durability: The rutile structure and Zr/Al coatings provide medium durability, making it suitable for both interior and exterior applications.
• Low Oil Absorption: The low oil absorption (16-20 g/100g) reduces the need for additional binders, lowering production costs.
• Chemical Stability: SR-2377 exhibits excellent resistance to UV light, heat, and moisture, ensuring long-term performance in harsh environments.

Applications in Industry

SR-2377 is a versatile pigment with applications across multiple industries:

• Coatings: Ideal for interior and exterior paints, powder coatings, and emulsion paints, where its high gloss and durability are critical.
• Inks: Used in inkjet inks and offset inks for printing on paper, plastics, and textiles, ensuring vibrant and fade-resistant colors.
• Plastics: Enhances the whiteness and UV resistance of plastic products, such as packaging materials and automotive components.
• Rubber and Masterbatches: Provides consistent coloration and improves the mechanical properties of rubber compounds and polymer masterbatches.
• Other Applications: Suitable for paper coatings, ceramics, and cosmetics, where its chemical stability and optical properties are beneficial.
