The Key to Enhancing Opacity: Technical Advantages of Rutile Titanium Dioxide

n the coatings, plastics, and paper industries, the choice of white pigment directly determines the visual quality and lifespan of the final product. Among the various options available, Rutile Titanium Dioxide has established itself as the irreplaceable material of choice due to its unique optical properties and chemical stability. As a professional supplier of chemical raw materials, Hanwu Technology is dedicated to providing high-quality Titanium Dioxide solutions to our global clients.

Why Choose Rutile Grade?

Compared to Anatase grade, Rutile Titanium Dioxide possesses a higher refractive index (approximately 2.71), which translates to superior light-scattering capabilities. In practical applications, this physical characteristic delivers two core advantages:

1. Superior Opacity and Tinting Strength: At the same film thickness, coatings formulated with high-quality Rutile TiO2 can cover the substrate color more effectively. For manufacturers, this implies that pigment dosage can be optimized in formulations, reducing overall costs without compromising quality.
2. Excellent Weather Resistance (Chalking Resistance): Outdoor coatings are constantly exposed to UV radiation and moisture, leading to potential “chalking.” Our Rutile TiO2 undergoes specialized surface treatments (such as Zirconium and Aluminium coating) to effectively shield the resin from UV degradation, significantly extending the outdoor service life and gloss retention of the end product.

Broad Industrial Applications

The general-purpose and specialized Rutile Titanium Dioxide supplied by Hanwu Technology is widely used in:

• Architectural and Industrial Coatings: Providing high brightness and a lasting pure white appearance.
• Plastic Masterbatches: Maintaining excellent dispersibility and resistance to yellowing even under high-temperature processing conditions.
• High-end Inks: Ensuring clear patterns and saturated colors in printing.

Technical Support and Commitment

We understand that pigment dispersibility directly impacts factory production efficiency. Therefore, we strictly control oil absorption and particle size distribution during our quality control process. This ensures that every batch disperses rapidly in our customers’ grinding equipment, preventing screen clogging and boosting production capacity.
