The Invisible Shield: Why TiO2 Surface Treatment Determines Everything

December 26, 2025 •

Without surface treatment, Titanium Dioxide is essentially unusable in industrial applications. Think of raw TiO2 as a “hyperactive troublemaker”—highly reactive to UV light and difficult to mix. The difference between a generic commodity grade and a high-performance pigment from top-tier manufacturers lies entirely in the “Coating”—the microscopic armor that dictates weatherability, dispersion, and oil absorption. This guide breaks down the difference between Inorganic and Organic treatments and how to read a chemical datasheet to find the perfect grade for your specific application.

Iron Oxide Pigment: Manufacturing, Applications, and Color Control

May 20, 2025 •

Iron oxide pigments are widely used inorganic colorants known for their durability, non-toxicity, and rich range of hues. Produced through either dry (thermal) or wet (precipitation) methods, these pigments appear in applications from construction and coatings to plastics and asphalt. This article explores how production processes influence color formation, how particle size affects hue brightness or depth, and how different color indexes like R110 or R180 are defined. Whether in vivid reds or earthy yellows, iron oxide pigments offer versatile and stable performance across industries.

Application of PVA in Warp Sizing

May 15, 2025 •

Polyvinyl Alcohol (PVA) is a widely used warp sizing agent valued for its excellent adhesion to both hydrophilic and hydrophobic fibers. It forms tough, abrasion-resistant films and blends well with other sizing agents like starch and polyacrylic acid, enhancing overall sizing performance. Fully hydrolyzed PVA offers strong adhesion but is difficult to dissolve and desize, while partially hydrolyzed grades are easier to handle but prone to foaming. Although PVA is non-toxic, its slow biodegradability limits its environmental appeal. Efforts are ongoing to improve its eco-friendliness and adapt its properties to modern high-speed weaving requirements. Despite these challenges, PVA remains one of the most effective and reliable textile sizing materials in use today.

Sulphate vs. Chloride Process Titanium Dioxide: Which Is Better for Coatings?

April 27, 2025 •

The coatings industry is the largest consumer of titanium dioxide (TiO₂), especially rutile-type titanium dioxide, with most of it being consumed by the paint and coatings sector. Globally, TiO₂ consumption by the coatings industry accounts for about 58%–60% of the total titanium dioxide pigment usage. In China, this proportion is even higher, around 60%–65%. Titanium dioxide is the most widely used pigment in the coatings industry, accounting for half of the pigment costs and approximately 90% of the total pigment consumption in the industry. It also represents about 10%–25% of the raw material costs in coatings.
