In the modern paint manufacturing industry, titanium dioxide (TiO₂) is the primary pigment component, widely used in architectural coatings, automotive paints, and industrial coatings. Its exceptional opacity, high brightness, and weather resistance make it the preferred material in the global coatings industry. As a professional manufacturer, we are committed to producing high-quality titanium dioxide using advanced chloride process technology to meet the market demand for high-performance coatings.

Chloride Process TiO₂: High-Purity, High-Performance Production Technology

Titanium dioxide production mainly employs two processes: sulfate process and chloride process. The chloride process is preferred for high-end coatings and specialized applications due to its superior purity, uniform particle size, and enhanced whiteness. The chloride process for titanium dioxide production includes the following steps:

Chlorination Reaction: High-grade rutile ore reacts with chlorine (Cl₂) and a reducing agent (such as petroleum coke) at high temperatures to produce titanium tetrachloride (TiCl₄).

Purification and Refinement: TiCl₄ undergoes distillation to remove impurities, ensuring high purity.

Oxidation Process: The purified TiCl₄ is oxidized at high temperatures to form high-crystallinity TiO₂.

Surface Treatment: Various surface coating techniques are applied to improve the dispersion, weather resistance, and photodegradation resistance of titanium dioxide in paints.

Our chloride process TiO₂ features finer particle size distribution and superior optical properties, making it widely applicable in premium paints, plastics, and printing inks.

The Key Role of Titanium Dioxide in Paints

Titanium dioxide is an essential component in modern paints, offering the following advantages:

Excellent Opacity and Brightness: TiO₂ has a high refractive index (2.7), effectively reflecting light to enhance the whiteness and brightness of coatings.

Superior Weather and Durability Resistance: Specially treated TiO₂ enhances a coating’s UV resistance, prolonging its lifespan.

Good Dispersion and Stability: High-quality titanium dioxide ensures uniform distribution in paint formulations, providing a smooth and even finish.

Applications of TiO₂ Coatings

As a specialized manufacturer, we produce high-performance TiO₂ that is widely used in the following areas:

Architectural Coatings: Enhances exterior coatings with stain resistance and weather durability, maintaining long-lasting color stability.

Automotive Paints: Improves gloss, scratch resistance, and durability of automotive coatings.

Industrial Coatings: Applied to steel structures, ships, and machinery for excellent corrosion and oxidation resistance.

Functional Coatings: Used in photocatalytic self-cleaning coatings, which decompose pollutants through TiO₂’s photocatalytic properties, applicable in glass facades and air-purifying coatings.

High-quality titanium dioxide coatings not only enhance paint performance but also drive the coatings industry toward more environmentally friendly and efficient solutions. As a manufacturer, we continuously optimize the chloride process TiO₂ production technology to provide superior coating materials for the architectural, automotive, industrial, and functional coatings markets. Moving forward, we remain committed to innovation and technological advancements, delivering top-tier titanium dioxide products and coating solutions to customers worldwide.
