Particle Size
The specially designed hydrolysis process results in R299+ having a fine particle size, yielding a white tint, blue undertone, and excellent hiding power.
Surface Treatment
R299+ is treated with advanced zirconium and aluminium compounds, significantly enhancing hiding power, gloss, and weather resistance. The organic treatment further improves dispersibility, making it suitable for various application systems.
Particle Size Distribution
R299+'s particle size distribution is consistent due to rigorous hydrolysis and calcination controls, ensuring superior gloss, dispersibility, and colour strength.
Applications
R299+ is suitable for various applications, including indoor and outdoor coatings, powder coatings, colour masterbatches, and various plastic systems.
The key benefits of this application are as follows:
Blue Undertone
The small, uniform particles effectively scatter blue light, resulting in a blue undertone and excellent whiteness.
High weather resistance
The product offers high weather resistance. Thanks to its advanced surface treatment, R299+ is highly durable in many environments.
Excellent dispersibility
The product displays excellent dispersibility. Inorganic and organic surface treatments prevent particle coalescence, improving application systems' dispersibility.
Lower oil absorption
The product exhibits low oil absorption. The product's low oil absorption rate improves wettability and dispersion, offering a cost-effective solution.
This comprehensive product is ideal for industries requiring high-quality, versatile titanium dioxide for general use.
