High-purity anatase titanium dioxide grades optimized for powder coating applications
Titanium Dioxide (TiO₂) exists in three natural crystal forms: anatase, rutile, and brookite. Among these, anatase titanium dioxide has carved out a unique and growing role in the powder coatings industry. With its distinctive crystal structure, anatase TiO₂ delivers exceptional whiteness, outstanding optical brightness, and superior surface gloss — properties that are critical for decorative and functional powder coating applications.
In powder coatings, the pigment must not only deliver color and opacity but also integrate seamlessly into the dry mixing and extrusion process. Anatase TiO₂ excels here due to its lower hardness (Mohs 5.5–6 vs. rutile's 6–6.5), which reduces equipment wear during manufacturing, and its excellent dispersibility in polymer matrices. This ensures uniform particle distribution, resulting in smooth, defect-free coating films.
Unlike rutile TiO₂, which is preferred for outdoor applications due to its superior UV resistance, anatase TiO₂ is particularly suited for indoor powder coating systems — including furniture, metal shelving, electrical enclosures, and consumer appliances — where long-term weathering resistance is less critical than optical performance and surface aesthetics.
The global powder coatings market has been on a robust growth trajectory, driven by increasing environmental regulations that favor solvent-free, VOC-free coating technologies. Powder coatings, as a zero-emission alternative to liquid paints, have seen accelerating adoption across automotive, construction, and consumer goods sectors. This macro trend directly elevates demand for high-quality anatase TiO₂ as a core pigment ingredient.
Understanding the commercial and industrial dynamics shaping anatase TiO₂ demand in powder coatings
The global powder coatings market was valued at over USD 12 billion in 2023 and is projected to exceed USD 18 billion by 2030, growing at a CAGR of approximately 6.5%. Asia-Pacific, led by China and India, accounts for the largest share of consumption, with Europe and North America following due to stringent VOC regulations. This sustained growth creates a structurally expanding demand base for anatase TiO₂ pigments.
Increasingly strict environmental regulations — including the EU's REACH directive, China's national emission standards, and US EPA guidelines — are accelerating the shift from solvent-borne liquid paints to powder coatings. Powder coatings produce zero VOC emissions and generate minimal waste, aligning perfectly with global sustainability goals. Anatase TiO₂, as a non-toxic, chemically stable white pigment, fits naturally into these eco-friendly formulations.
China is the world's largest producer and exporter of titanium dioxide, including both anatase and rutile grades. Chinese manufacturers have significantly upgraded their production technologies, achieving international quality standards while maintaining competitive pricing. This positions Chinese anatase TiO₂ suppliers as indispensable partners for global powder coating manufacturers seeking reliable, cost-effective pigment supply chains.
Modern anatase TiO₂ grades for powder coatings are no longer simple raw pigments. Advanced surface treatment technologies — including alumina, silica, and organic coating modifications — significantly enhance dispersibility, reduce agglomeration, and improve compatibility with polyester, epoxy-polyester, and TGIC-free resin systems. These innovations allow formulators to achieve higher pigment volume concentrations (PVC) without sacrificing film quality or gloss levels.
From architectural metalwork to precision electronics — where anatase TiO₂ delivers the most value
Key technical parameters and formulation considerations for powder coating engineers
Anatase TiO₂ typically achieves a whiteness index (WI) of 95–98 and a brightness (L*) of 98–99.5 in powder coating films. Its lower refractive index (2.55) compared to rutile (2.73) results in a softer, blue-toned white that is highly preferred in interior design and consumer product aesthetics. The high optical scattering efficiency ensures excellent hiding power even at moderate loading levels of 15–25% by weight.
In powder coating manufacturing, TiO₂ is dry-blended with resins, curing agents, and additives before extrusion. Anatase TiO₂'s lower Mohs hardness reduces wear on extruder screws and barrels. Its surface-treated grades exhibit excellent dispersibility in polyester and epoxy-polyester systems, achieving fine particle size distribution (D50: 0.2–0.4 μm) that translates directly to smooth, high-gloss coating films with minimal orange peel defects.
Anatase TiO₂ contributes significantly to the gloss level of powder coatings. High-purity anatase grades with controlled particle size distribution (narrow PSD) enable formulators to achieve 60° gloss values of 85–95 GU in standard polyester-based powder coatings. This is particularly important for appliance coatings and decorative metalwork where surface aesthetics are a primary customer requirement.
Anatase TiO₂ demonstrates excellent compatibility across the major powder coating resin systems: polyester/TGIC, polyester/HAA (TGIC-free), epoxy/polyester hybrid, and pure epoxy. Surface-treated grades with alumina and silica coatings provide enhanced wetting and reduced agglomeration in all these systems. For UV-curable powder coatings — a rapidly growing segment — anatase TiO₂ is particularly advantageous due to its compatibility with photoinitiator systems.

Two decades of expertise in titanium dioxide for coatings, plastics, and industrial applications
The company's founder entered the titanium dioxide industry, starting in a production technology position. He gained in-depth knowledge of titanium dioxide manufacturing principles and application requirements, subsequently transitioning to a technical sales role, earning market and customer trust through professional expertise in coatings and pigment systems.
Asia Pacific Chemical was officially established, and since then, it has independently distributed products from multiple well-known manufacturers to global customers, continuously growing and expanding its portfolio of anatase and rutile TiO₂ grades for powder coatings, liquid coatings, plastics, and inks.
We contracted and operated our first production line, officially launching our own brand. Simultaneously, we established a comprehensive quality testing laboratory and a modern warehousing system (with an inventory capacity of approximately 2,000 tons). Currently, the company has formed a multi-engine collaborative model of "distribution and agency + independent production + technical services," capable of covering a wider range of market demands across the global powder coatings industry.
