Titanium Dioxide Pigment in Architectural Coatings

• In architectural coatings, titanium dioxide pigment is a cornerstone for durability enhancement. Its high TiO2 content, with a minimum of 93.0%, ensures excellent hiding power, effectively covering the substrate and providing a uniform appearance. This not only improves the aesthetic appeal of buildings but also serves as the first line of defense against environmental elements. The close whiteness to the standard sample imparts a bright and clean look to the coatings, which is highly desired in architectural applications. The rutile content of 98% contributes to superior weather resistance. Rutile - based titanium dioxide pigment can effectively block ultraviolet (UV) rays, preventing the coating from premature aging, fading, and chalking. As a result, architectural coatings formulated with this pigment maintain their color and integrity over an extended period, even when exposed to harsh sunlight, rain, and wind.

• The surface treatment with aluminum and silicon further enhances the performance of titanium dioxide pigment in architectural coatings. This treatment improves the pigment's dispersion in the coating matrix, ensuring a consistent distribution throughout the film. A well - dispersed pigment creates a continuous and dense protective layer on the surface, enhancing the coating's resistance to dirt, moisture, and chemical contaminants. The low matter soluble in water (0.5 max %) and the controlled pH of the aqueous suspension (6.5 – 8.0) prevent the pigment from reacting with water - based coating components, ensuring the stability of the coating formulation. Additionally, the low oil absorption (21.0 max %) allows for better control of the coating's viscosity and drying properties, facilitating easy application and achieving a smooth finish. All these properties combined make titanium dioxide pigment an indispensable ingredient for durable architectural coatings, enabling wholesalers to offer products that meet the long - term protection and aesthetic requirements of building projects.

Titanium Dioxide Color in Industrial Coatings

• Titanium Dioxide Color is of great significance in industrial coatings, where durability and performance are paramount. The high tint reducing power of at least 100%, compared to the standard sample, allows for the creation of coatings with intense and consistent colors. In industrial settings, such as machinery, equipment, and automotive parts, a vibrant and long - lasting color not only enhances the visual appeal but also serves as an indicator of quality and brand identity. The excellent weather resistance provided by the titanium dioxide color ensures that the industrial coatings can withstand the rigors of industrial environments, including exposure to chemicals, abrasion, and extreme temperatures. The rutile form of the pigment, with its 98% content, offers superior protection against UV - induced degradation, preventing the coating from cracking, peeling, and losing its color over time.

• The low residue on sieve (0.10 max %) and the fine particle size of titanium dioxide color contribute to a smooth and even coating film. This not only improves the appearance of the coated surface but also enhances the coating's resistance to wear and tear. A smooth surface reduces the accumulation of dirt and debris, making it easier to clean and maintain. The controlled water content (0.05 max %) and high resistivity in water extraction (90.0 min) ensure that the pigment is stable in both water - based and solvent - based industrial coating systems. This stability is crucial for maintaining the coating's performance and durability during the manufacturing process and in the long - term use of the coated products. Tangshan Dachuan Machinery Co.,ltd.'s titanium dioxide color products, with their optimized properties, provide industrial coating manufacturers with the means to produce high - quality, durable coatings that can withstand the harsh conditions of industrial applications, enabling wholesalers to meet the demanding needs of their industrial customers.

Ti02 Pigment and Coating Durability Mechanisms

• Ti02 Pigment enhances coating durability through multiple mechanisms. Its high refractive index, a characteristic of titanium dioxide, contributes to the coating's ability to scatter light, providing excellent hiding power and opacity. This property not only improves the visual appearance of the coating but also protects the underlying substrate from UV radiation and other environmental factors. The rutile crystal structure of Ti02 Pigment is highly resistant to chemical and physical degradation, making it ideal for long - term exposure to various environmental conditions. The surface treatment with aluminum and silicon creates a protective barrier around the pigment particles, preventing them from reacting with the coating matrix and other components. This barrier also improves the pigment's compatibility with the coating resin, resulting in better adhesion and a more uniform coating film.

• The low matter soluble in water and the controlled pH of Ti02 Pigment ensure its stability in different coating formulations. This stability is essential for maintaining the coating's integrity over time, as any chemical reactions within the coating can lead to degradation and reduced durability. The low oil absorption of the pigment allows for more efficient use of binders and other additives in the coating formulation, optimizing the coating's performance and durability. Additionally, the fine particle size and low residue on sieve ensure a smooth and consistent distribution of the pigment in the coating, creating a continuous and protective layer on the surface. All these mechanisms work together to enhance the overall durability of coatings containing Ti02 Pigment, making it a preferred choice for coating manufacturers seeking to produce long - lasting and reliable products. Wholesalers can leverage this knowledge to promote the benefits of Ti02 Pigment to their customers and differentiate their product offerings in the market.
