CR537 Rutile Grade Titanium Dioxide Especially for Papermaking
CR537 is a silicon, aluminum inorganic and organic surface treated rutile titanium dioxide, with its average particle size distribution, good water dispersion, good hiding power and high weather resistance properties. It is mainly used in water-based system which demand high water dispersion, such as paper-making, water-based coatings (especially interior and exterior latex paints), and water-based ink production

The product's small particle size, achieved through a precisely controlled hydrolysis process, produces a brighter tint, a blue undertone, and superior hiding power.
The product has undergone a surface treatment process. Combining a high-quality aluminium-based inorganic coating and a special organic surface treatment optimises CR537 for excellent optical properties and overall performance.
The finely distributed particles, resulting from our advanced hydrolysis and calcination processes, provide CR537 with exceptional gloss, dispersion, and excellent tinting strength and opacity.
Potential applications include CR537, which is suitable for many applications, including masterbatches, profiles, sheets, and pipes made from polyolefin, PVC, ABS, and PS. Furthermore, it is an excellent choice for use in leather colour pastes.
CR538 is versatile, catering to indoor and outdoor coatings, powder coatings, colour masterbatches, and various plastic systems.
Key application benefits include:
Blue undertone tint
The fine particles and uniform distribution produce a distinctive blue hue and impressive whiteness.
High weather resistance
Unique surface treatments enhance its dispersibility and weather resistance in application systems.
High temperature resistance
This product exhibits high resistance to yellowing during high-temperature processing.
Lower oil absorption
The product exhibits low oil absorption and is excellently compatible with plastic resins, ensuring superior melt fluidity.
