Titanium dioxide (TiO₂) is a critical inorganic chemical with widespread applications in coatings, papermaking, plastics, ceramics, and more. Among its forms, Rutile Titanium Dioxide stands out for its exceptional chemical stability, high whiteness, and superior performance. One such product, SR-2377, is a specialized rutile titanium dioxide pigment designed for ink production and other industrial applications. 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 is a rutile titanium dioxide pigment that undergoes surface treatment with zirconium (Zr) and aluminum (Al), combining inorganic and organic modifications. This unique treatment enhances its performance in terms of gloss, durability, and dispersion. The product is tailored for applications requiring high-quality white pigments, such as interior and exterior coatings, emulsion paints, powder coatings, inks, primers, rubber, masterbatches, and plastics.

One of the key features of SR-2377 is its high titanium dioxide content (≥93%) and rutile content (≥97%), which contribute to its excellent light-scattering properties and chemical stability. The organic treatment ensures improved compatibility with various binders and resins, while the inorganic coating (Zr and Al) enhances its resistance to UV degradation and weathering.

The technical specifications of SR-2377 highlight its superior quality and performance. For instance, the high tinting strength (≥180%) ensures that even small quantities of SR-2377 can achieve vibrant white hues, reducing the need for excessive pigment usage. Its low oil absorption (16–20 g/100g) makes it ideal for use in low-viscosity systems, such as water-based inks and coatings. Additionally, the high specific resistance (≥8000 Ω·cm) indicates excellent electrical insulation properties, which are critical in electronic and industrial applications.

Applications

SR-2377 is a versatile pigment suitable for a wide range of industries. Its excellent gloss and durability make it a preferred choice for interior and exterior coatings, where long-term color retention and resistance to environmental factors are essential. In the paint and ink industry, SR-2377 enhances the whiteness and opacity of formulations, ensuring consistent color quality and improved coverage.

In the plastics and rubber industry, SR-2377 provides UV resistance and thermal stability, preventing discoloration and degradation under prolonged exposure to sunlight. For masterbatches and color concentrates, its good dispersion properties ensure uniform color distribution, reducing the risk of uneven coloring in end products.

For papermaking, SR-2377 improves the brightness and printability of paper, making it ideal for high-quality printing applications. Its chemical inertness also makes it suitable for use in cosmetics and pharmaceuticals, where safety and stability are paramount.
