⭐ What Is Titanium Dioxide (TiO₂)?

Titanium Dioxide (TiO₂) is an inorganic white pigment known for its exceptional whiteness, high opacity, and strong light-scattering ability (high refractive index).
It is the most widely used white pigment in the world, essential in the paint, plastic, coating, ink, paper, cosmetics, food, and chemical industries.

TiO₂ exists mainly in two crystal forms: rutile and anatase.
Rutile TiO₂ is the most preferred form due to its superior stability and UV resistance.

🔧 What Is TiO₂ Used For?

The primary functions of Titanium Dioxide include:

✔ 1. Providing Whiteness & Color Strength (White Pigment)

TiO₂ is the strongest white pigment globally, giving brilliant whiteness and strong opacity.

✔ 2. UV Protection

TiO₂ absorbs and reflects UV radiation, improving:

• Weather resistance
• Durability
• UV stability

in paints, coatings, plastics, and sunscreens.

✔ 3. Gloss & Matte Control

Depending on the grade, TiO₂ can create:

• High gloss
• Matte finishes

✔ 4. Improved Mechanical & Chemical Durability

Enhances coating performance by increasing scratch resistance, longevity, and chemical stability.

✔ 5. High Hiding Power (Opacity)

Even at low dosages, TiO₂ completely covers underlying surfaces—critical for paint and coating formulations.

🎯 Purposes of TiO₂

✔ 1. Paint & Coating Industry (Largest Application)

Used in:

• Interior/exterior paints
• Industrial coatings
• Primers
• Automotive coatings

to provide brightness, opacity, and UV protection.

✔ 2. Plastics Industry

In PVC, PP, PE, PET, and other plastics, TiO₂ acts as:

• Pigment
• UV stabilizer
• Durability enhancer

✔ 3. Paper Industry

Provides whiteness, brightness, and opacity to paper products.

✔ 4. Inks & Printing Systems

Enables vivid, high-resolution printing.

✔ 5. Cosmetics & Sunscreens

Used as:

• UV filter
• Whitening pigment

✔ 6. Food Industry (E171 – restricted or banned in some countries)

Historically used as a whitening agent in food products.

✔ 7. Ceramics & Glass Industry

Provides heat resistance and opacity in ceramic and glass formulations.
