1. Coatings

The coatings industry is the largest consumer of titanium dioxide pigments, accounting for approximately 58% to 60% of the global consumption of TiO&#; pigments. Coatings encompass a broad range of products, including paints, varnishes, and finishes. These products can be solvent-based or water-based and include powder coatings and UV-cured coatings.

Titanium dioxide is the most widely used pigment in the coatings industry due to its excellent properties. It provides bright and vivid colors, high opacity, strong tinting strength, and superior weather resistance. These attributes make coatings produced with TiO&#; more durable and effective at protecting and decorating surfaces. The primary applications of TiO&#; pigments in coatings include:

 

• Automotive Coatings: Used for both aesthetic and protective purposes.
• Architectural Coatings: Includes paints for buildings and structures, with latex paints being a significant segment.
• Industrial Coatings: Applied to machinery, appliances, and other equipment.
• Marine Coatings: Used on ships and offshore structures for protection against harsh marine environments.
• Specialty Coatings: Includes coatings for toys, household items, and decorative objects.

2. Plastics

Plastics are the second largest market for titanium dioxide, consuming about 18% to 20% of the global supply. In plastics, TiO&#; pigment is valued for its ability to enhance whiteness, opacity, and UV resistance. It helps improve the heat and light stability of plastic products, preventing degradation from UV exposure. Its fine particle size and uniform distribution enhance the quality of the plastic by providing better reflectivity of light and improved mechanical properties.

 

Common applications of TiO&#; pigments in plastics include:

 

• Packaging: Films, bottles, and containers that require high opacity and aesthetic appeal.
• Construction Materials: Pipes, sidings, and fittings that benefit from enhanced durability.
• Consumer Goods: Household items, toys, and electronic housings.
• Automotive Parts: Interior and exterior plastic components.

3. Paper

Titanium dioxide is the third most significant application area for TiO&#; pigments, particularly in the United States, where it is the second largest market. In the paper industry, TiO&#; is used to improve the brightness, opacity, and printability of paper. It is essential in producing high-quality paper products, including:

 

• Fine Papers: Used in books, magazines, and high-quality printing materials.
• Thin Papers: Such as those used in dictionaries and high-end magazines.
• Specialty Papers: Including banknotes, computer paper, and decorative papers.

 

The use of TiO&#; in paper results in superior whiteness, gloss, and smoothness, enhancing the overall quality and usability of the paper.

4. Rubber

In the rubber industry, titanium dioxide is used not only as a pigment but also for its reinforcing and filler properties. It helps improve the durability, aging resistance, and mechanical strength of rubber products. TiO&#; is particularly important in:

 

• Tires: Especially the white sidewalls of car tires.
• Footwear: Including sports shoes and rubber boots.
• Rubber Flooring: Providing color and strength to flooring materials.
• Miscellaneous Products: Such as gloves, raincoats, and sporting goods.

5. Chemical Fibers

Titanium dioxide is crucial in the chemical fiber industry, particularly for synthetic fibers. It serves as a delustering agent, reducing the shine of fibers by scattering light. This is essential for producing fibers with a matte finish. Synthetic fibers, including nylon, polyester, and rayon, benefit from the inclusion of TiO&#; due to its high refractive index and optimal particle size distribution.

6. Inks

In the ink industry, titanium dioxide pigment is a vital component due to its high opacity and tinting strength. It is used in various types of inks, including those used for printing newspapers, books, magazines, and packaging materials. TiO&#; ensures high-quality prints with excellent color consistency and durability. Specific uses include:

 

• White and Light-Colored Inks: Providing opacity and brightness.
• Specialty Inks: Used for printing on metals, ceramics, and plastics.

Titanium Dioxide Pigment Processing Matters

Painting takes time &#; and it's expensive. When homeowners make the investment to update the color in their homes, they expect high standards of durability, appearance, and opacity without the need for frequent touch-ups or re-coats.

High-quality paints that use premium titanium dioxide (TiO&#;) benefit from the pigment's exceptional characteristics &#; including high brightness and a very high refractive index &#; which makes TiO&#; the most widely-used white pigment in paints today. Adding TiO&#; to paints improves characteristics like color and gloss retention, dispersibility, ease of application, whiteness, and brightness.

This paper explains the difference between the two methods used to process TiO&#;: Sulfate manufacturing and chloride manufacturing. Of the two processes, you'll learn how the chloride manufacturing process has a lower environmental footprint and generates less waste. Companies that produce TiO&#; via the chloride manufacturing process &#; like Chemours &#; also conduct a variety of tests to ensure the pigment's efficacy.
