Anatase and Rutile TiO₂: Choosing the Right Titanium Dioxide Grade for Your Application

 Anatase and Rutile TiO₂ are two forms of titanium dioxide (Tioxin). Both pigments have many different uses all around the world, i.e., Paint, Coatings, Plastics, Paper,  etc. They rank among the largest users of pigments in the world today. Each offers excellent white pigments and provides excellent whiteness, performance, durability, and cost effectiveness. As such, International Manufacturers and Importers should take a well-informed approach in the selection of the proper grade of titanium dioxide (Tioxin) to achieve the desired high-quality, consistent, and long-life product.

At Sukhmani Impex, we collaborate with our customers around the globe to provide the right titanium dioxide solutions for specific applications according to International Quality Standards.

Our Titanium Dioxide (Tioxin) is comprised of high-quality Anatase grades, including SA-216, SA-171, and High Performance Rutile grades, including DR-2000, DR-2100, DR-2200, DR-945, DR-900+, DR-2400, DR-2400+, DR-2450, DR-945+ for many different industries.

This guide outlines the main differences between Anatase and Rutile TiO₂  and should help you determine which grade will best fit your industry.

Understanding Anatase and Rutile TiO₂

Titanium Dioxide (Tioxin) is found naturally in several crystalline forms. However, only two crystalline forms of titanium dioxide, Anatase and Rutile, are commercially available. Both are used as white pigments; optical properties, crystal structures, and resistance to degradation vary greatly between the two forms of titanium dioxide. 

The decision between the two grades of titanium dioxide depends on the following:

• The amount of brightness and opacity needed.  
• The amount of UV light exposure and weathering that may occur.
• The application environment (indoor or outdoor).
• The cost associated with the product. 
• The applicable performance standards for the industry.

What Is Anatase Titanium Dioxide?

Anatase TiO₂  is known for its brilliance, whiteness and colour purity as well as having a lower refractive index in comparison to Rutile Grade of TiO₂. This means that the pigment will be brighter.

however, it does have a lower opacity and durability. The Anatase Types of TiO₂ are easy to process and have excellent dispersion properties, making them ideal for uses that require a smooth, high-whiteness surface. Due to their relatively low abrasivity, these are very commonly used in many products, including papers,  fibres, rubber and some plastics.

In addition to providing excellent dispersion and ease of processing, the Anatase TiO₂ also offers a high degree of chemical stability and resistance to yellowing over time, which allows you to keep the appearance of the product for a longer period of time. The only drawback to using this type of TiO₂ is Inferior weathering stability, which limits its use for outdoor long-term applications.

Sukhmani Impex supplies reliable, high-brightness Anatase Titanium Dioxide (TIOXIN™) grades with uniform dispersion:

• SA-171 – A cost-effective grade primarily suited for indoor applications.
• SA-216 – Designed for applications requiring very high brightness.

Key Characteristics of Anatase TiO₂

• Anatase TiO2 has a very high brightness and white colour.
• It has excellent tinting strength.
•  Is easy to disperse in water-based systems.
• Anatase TiO2 has a lower density than Rutile TiO2 and is, therefore, less expensive to produce.
• The UV and weathering resistance of Anatase TiO2 is limit.

Anatase Titanium Dioxide for Paper, Plastics & Rubber Applications

Anatase Titanium Dioxide provides excellent whiteness, colour purity, and light scattering capabilities resulting in a bright and smooth finish. Anatase Titanium Dioxide is very suitable for applications with a required high level of optical performance, low abrasiveness, and ease of processing.

• TIOXIN™ SA-216 is widely used in paper, plastics, and rubber applications where high brightness is essential.

• TIOXIN™ SA-171 offers a cost-effective solution for achieving consistent whiteness in economical manufacturing processes.

Sukhmani Impex is a reputable Titanium Dioxide supplier and continues to deliver reliable and consistent (Tioxin) Anatase TiO₂ products to industries globally and meets the international requirements of quality.

Anatase Titanium Dioxide has common applications in:

• Coatings and uncoated papers.
• Low-abrasive applications and plastic compounds.
• Rubber consumer products.
• Indoor Paints & Special Coatings.

What Is Rutile Titanium Dioxide?

Rutile-grade titanium dioxide (TIOXIN™)  is the most common titanium dioxide pigment sold globally. It has a much higher refractive index compared to anatase Titanium and provides greater opacity, UV protection, durability and resistance to weathering.

Compared to Anatase, Rutile TiO₂ offers:

• Better light reflectivity.
• Higher hiding power.
• Excellent UV resistance.
• Superior long-term durability.

Sukhmani Impex supplies multiple Rutile Titanium Dioxide (TIOXIN™) grades:

• DR-945+ and DR-945 (Chloride process) – Ideal for premium coatings and plastic applications.
• DR-2400 and DR-2100 (Sulphate process) – Suitable for general industrial and plastic applications.

Key Characteristics of Rutile TiO₂ Pigment

• Opacity and Hiding Power.
• UV Protection.
• Weather Resistance and Durability are superior.
• Extreme Performance for outdoor applications.
• Available with a Surface Treatment or Untreated versions.

Rutile Titanium Dioxide for Paints and Coatings

Rutile Titanium Dioxide is used as a pigment in paints and coatings where exceptional durability and optical performance are needed. Rutile TiO₂ is used heavily in decorative paint, industrial coatings, and printing inks.

• TIOXIN™ DR-900+ Titanium Dioxide provides high brightness, excellent opacity, and strong weather resistance in high-quality, durable coatings for interior and exterior use.
• TIOXIN™ DR-2000 Titanium Dioxide offers extended durability in both brightness and weather resistance, providing top-quality protection in the most demanding conditions.
• TIOXIN™ DR-2100 Titanium Dioxide provides outstanding dispersibility, superior hiding power, and stable optical properties across high-end finishes for a wide range of coatings applications.
• TIOXIN™ DR-2200 Titanium Dioxide offers superior gloss retention, enhanced UV resistance, and increased opacity across high-performance finishes, providing a broad range of applications in demanding outdoor environments.
• TIOXIN™ DR-945 Titanium Dioxide delivers superior dispersion properties, improved tinting strength, and consistent colour performance across a variety of coating applications in a broad range of industrial environments.

Common Rutile TiO₂ Applications:

• Exterior paints and coatings.
• Industrial and automotive coatings.
• Plastics and PVC products.
• Masterbatch applications.

How to Choose Between Anatase and Rutile Titanium Dioxide

Choose Anatase Titanium Dioxide If:

• Your application is for indoor use or not exposed to direct sunlight
• Brightness is a higher priority than opacity
• Your industry is paper or printing inks
• Cost optimisation is a key consideration

Grades such as TIOXIN™ SA-216 and SA-171 are ideal choices.

Choose Rutile Titanium Dioxide Pigment If:

• You need a long service life for your product.
• UV resistance and weather stability are critical.
• You are developing exterior coatings or plastic materials.
• High opacity and excellent hiding power are required.

Grades such as TIOXIN™ DR-945+, DR-945, DR-2400, and DR-2100 are recommended.

Importance of Testing Before Bulk Procurement

Performance testing is essential for all international buyers, especially for a large volume of purchases. 

Performance Testing should include:

• Measurement of brightness and opacity.
• Testing and comparison of tinting strength.
• Assessment of pigment behaviour during dispersion.
• Evaluation of the pigment’s UV resistance.
