The CR538 achieves a fine particle size through a meticulously designed hydrolysis process, delivering a bright white tint, blue undertone, and strong hiding power.
With advanced zirconium and aluminium compound treatments, CR538 offers enhanced hiding power, gloss, and weather resistance. The organic surface treatment further optimizes dispersibility, making it ideal for diverse applications.
CR538 maintains a uniform particle size distribution due to precise hydrolysis and calcination processes, ensuring excellent gloss, dispersibility, and vibrant colour strength.
CR538 is versatile, catering to indoor and outdoor coatings, powder coatings, colour masterbatches, and various plastic systems.
Key application benefits include:
Blue Undertone
The uniform and finely distributed particles scatter blue light effectively, resulting in a blue undertone and superior whiteness.
High Weather Resistance
Thanks to advanced surface treatments, CR538 exhibits outstanding durability in different environments, ensuring long-lasting performance.
Excellent Dispersibility
The product's inorganic and organic surface treatments minimize particle clumping, improving dispersibility in a range of systems.
Lower Oil Absorption
CR538's low oil absorption enhances wettability and dispersion, providing a cost-efficient solution.
This high-quality product is an excellent choice for industries seeking reliable and versatile titanium dioxide for general applications.
