The CR539 features a fine particle size achieved through a specialized hydrolysis process, providing exceptional whiteness, a blue undertone, and outstanding hiding power.
Advanced zirconium and aluminium compound treatments significantly boost CR539's hiding power, gloss, and weather resistance. Organic treatment further enhances its dispersibility, making it versatile for various application systems.
With strict hydrolysis and calcination controls, CR539 ensures a uniform particle size distribution, leading to superior gloss, dispersibility, and vibrant colour strength.
CR539 is highly adaptable, serving indoor and outdoor coatings, powder coatings, colour masterbatches, and various plastic systems.
Key application benefits include:
Blue Undertone
The finely dispersed particles effectively scatter blue light, delivering a blue undertone and excellent whiteness.
High Weather Resistance
Thanks to advanced surface treatments, CR539 offers remarkable durability in diverse environments, ensuring extended performance.
Excellent Dispersibility
The combination of inorganic and organic surface treatments prevents particle agglomeration, enhancing dispersibility across various systems.
Lower Oil Absorption
CR539's low oil absorption rate improves wettability and dispersion, optimizing cost efficiency.
This versatile and high-quality product is well-suited for industries seeking reliable titanium dioxide solutions for general use.
