    Frequently Asked Questions
    Q What is NTR-606 titanium dioxide and what type of crystal structure does it have?
    NTR-606 is a super durability rutile-type titanium dioxide pigment. It has a rutile content of 99.5%, which provides excellent UV resistance, superior whiteness, and high refractive index compared to the anatase form, making it ideal for demanding industrial applications.
    Q What surface treatment does NTR-606 use, and why does it matter?
    NTR-606 uses advanced aluminum (Al) and zirconium (Zr) surface treatment combined with organic modification. This dual-layer treatment minimizes particle agglomeration, enhances dispersibility in both aqueous and solvent-based systems, and improves weatherability and durability in end-use applications.
    Q Which industries and applications is NTR-606 most suitable for?
    NTR-606 is widely used in paints and coatings (exterior/interior architectural, industrial maintenance, automotive), plastic manufacturing (PVC profiles, polyolefins, engineering plastics), and ink and paper coating industries. It is especially recommended for applications requiring excellent durability, high whiteness, and reliable processing performance.
    Q What are the key optical performance values of NTR-606?
    NTR-606 achieves a CIE L* value of 98.5, indicating exceptional whiteness, with a b* value of 1.8 for minimal yellowness. Its lightening power (Reynolds number) reaches 1920, reflecting outstanding tinting strength and opacity in finished products.
    Q Does NTR-606 comply with environmental and safety standards?
    Yes. NTR-606 meets strict environmental requirements. Heavy metal content (Pb, As, Hg, Cr6+) is below 10 ppm, and it contains no PBB or PBDE substances. It is compliant with ISO 591-1:2000 (R2) and ASTM D476:00 (Types II, III, IV) standards, supporting use in environmentally sensitive applications.
    Q What is the particle size and oil absorption of NTR-606, and how do these affect processing?
    NTR-606 has a controlled particle size of 0.28 microns and an oil absorption of 18 g/100g. The fine, uniform particle size ensures excellent dispersion and optical efficiency, while the low oil absorption allows for higher pigment loading with less binder, improving formulation flexibility and reducing overall production costs.
