Introduction to Anatase Titanium Dioxide

Anatase titanium dioxide is a crystalline form of titanium dioxide (TiO2) widely recognized for its exceptional whiteness, brightness, and photocatalytic activity. Compared with the rutile form, anatase has a slightly lower density and refractive index, but it is favored in many industries for its high dispersibility, excellent hiding power, and versatility in pigments. MA-66 anatase titanium dioxide is a premium-grade product designed to meet stringent application demands with superior process performance. In this blog post, ALATAI TIO2, a high grade anatase TiO2 manufacturing factory, will share the excellent industrial performance of anatase titanium dioxide for coatings.

MA-66 Anatase TiO2: Product Overview

MA-66 is a high-grade anatase titanium dioxide pigment characterized by outstanding purity, brightness, and uniformity. As a pigment under Color Index Pigment White 6, it is formulated to deliver high performance across a range of industrial applications. Its consistent quality makes it suitable for coatings, plastics, rubber, fibers, paper, and decorative materials.

Key specifications of MA-66 include:

• TiO2 Content: ≥99.2%

• L* (Brightness): ≥99.8

• b* (Color Tone): ≤0.5

• pH Range: 6.5–8.5

• Oil Absorption: ≤20 g/100g

• Tint-Reducing Power: ≥105

• Volatile Matter at 105℃: ≤0.4%

• Water-Soluble Substances: ≤0.6%

These values highlight the pigment’s stability, purity, and suitability for demanding formulations.

Unique Features of MA-66 Anatase Titanium Dioxide

High-quality anatase titanium dioxide pigments are defined by their ability to deliver uniform coverage, brightness, and dispersion. MA-66 stands out with the following features:

1. High Purity and Chemical Stability

With a TiO2 content of ≥99.2%, MA-66 ensures minimal contamination by impurities. High purity translates into reliable performance in sensitive applications such as paper production and fiber processing.

2. Exceptional Whiteness and Brightness

The superior L* value (≥99.8) reflects excellent whiteness and brightness. This ensures that coatings and decorative paints formulated with MA-66 anatase TiO2 maintain vivid, clean tones and high reflectivity.

3. Strong Hiding Power

One of the most valuable properties of anatase titanium dioxide pigments is hiding power, the ability to cover underlying colors. MA-66 demonstrates strong opacity, reducing the amount of pigment needed in formulations while maintaining coverage.

4. High Dispersibility

The controlled particle size and surface treatment of MA-66 enable excellent dispersibility in different media. This is particularly beneficial in coatings and rubber, where uniform distribution ensures consistent visual appearance and mechanical properties.

5. Balanced Oil Absorption

With an oil absorption value of ≤20, MA-66 anatase titanium dioxide balances pigment loading with binder compatibility, leading to smooth application and reduced viscosity issues in coatings and inks.

Applications of MA-66 Anatase TiO2

The versatility of MA-66 makes it suitable for multiple industrial sectors where whiteness, opacity, and consistency are essential.

1. Interior Coatings and Decorative Paints

Anatase titanium dioxide is widely used in architectural coatings due to its ability to produce bright, uniform finishes. MA-66 provides strong hiding power and enhances the aesthetic appeal of walls, ceilings, and decorative surfaces.

2. Rubber Industry

In rubber products, MA-66 anatase TiO2 acts as a reinforcing pigment while improving brightness and surface finish. It is suitable for footwear, hoses, and molded components.

3. Paper Making

The high brightness and dispersibility of MA-66 make it a preferred pigment for paper coatings, ensuring high opacity, smooth surface quality, and improved printability.

4. Leather and Fiber Applications

MA-66 is also used in artificial leather and fiber production. Its fine dispersion and whiteness provide enhanced color stability and surface appearance.

5. Plastics and Other Materials

In plastics, anatase titanium dioxide enhances brightness and opacity while maintaining compatibility with polymer matrices. Its balanced properties support wide usage in packaging and consumer goods.

Technical Advantages of Anatase Titanium Dioxide

While rutile titanium dioxide is often chosen for outdoor applications due to its superior UV resistance, anatase titanium dioxide provides unique benefits for indoor and specialty uses:

• Photocatalytic Properties: Anatase form is more active under UV light, making it suitable for applications where photocatalysis is desirable.

• Cost-Effectiveness: In many cases, anatase TiO2 offers high performance at a lower cost compared to rutile grades.

• Enhanced Dispersion: Its softer crystal structure supports easier milling and finer dispersion in coatings and papers.

Packaging and Handling of MA-66 Anatase TiO2

MA-66 is carefully packaged to maintain quality during transport and storage. Standard packaging consists of 25 kg multi-layer paper-plastic complex bags. For bulk requirements, customized packaging of 500 kg or 1,000 kg bags can be provided upon request.

Proper storage in dry, ventilated environments ensures that the pigment maintains its dispersibility and performance over time.

Why Choose MA-66 Anatase Titanium Dioxide?

The combination of high purity, strong hiding power, and superior whiteness positions MA-66 as a trusted choice for manufacturers seeking reliable pigment performance. Its balanced specifications make it adaptable across diverse industries without compromising on quality.

For businesses requiring a consistent supply of premium-grade anatase TiO2, MA-66 offers:

• Stable quality and reliable supply chain
