    Frequently Asked Questions
    Q What is NTR-606 titanium dioxide and what makes it a "super durability" grade?
    NTR-606 is a rutile-type titanium dioxide pigment with a TiO2 content of 94% and a rutile conversion rate of 99.5%. It is classified as super durability grade due to its advanced aluminum-zirconium (Al/Zr) surface treatment combined with organic modification, which significantly enhances its weather resistance, UV stability, and long-term performance in both exterior and interior applications.
    Q Which industries and applications is NTR-606 best suited for?
    NTR-606 is well suited for a wide range of industries including paints and coatings (exterior/interior architectural coatings, industrial maintenance paints, automotive finishes), plastic manufacturing (PVC profiles, polyolefin products, engineering plastics), as well as ink and paper coating applications requiring high brightness, opacity, and superior printability.
    Q What surface treatment does NTR-606 use and why does it matter?
    NTR-606 utilizes an aluminum and zirconium (Al/Zr) inorganic surface treatment combined with organic compound modification. This dual treatment minimizes particle agglomeration, improves dispersion in both aqueous and solvent-based systems, and enhances compatibility with various polymer matrices — resulting in better processing efficiency and more consistent final product quality.
    Q What are the key optical performance values of NTR-606?
    NTR-606 offers excellent optical performance with a CIE L* value of 98.5 (indicating very high whiteness), a b* value of 1.8 (low yellowness), and a lightening power (Reynolds number) of 1920. These values confirm its superior brightness and tinting strength, making it ideal for applications demanding premium white pigment performance.
    Q Is NTR-606 compliant with environmental and safety regulations?
    Yes. NTR-606 meets strict environmental and safety standards. Heavy metals including Pb, As, Hg, and Cr6+ are all below 10ppm, and it contains no PBB or PBDE substances. It complies with ISO 591-1:2000 (R2) and ASTM D476:00 (Types II, III, IV), making it suitable for use in regulated markets and environmentally conscious manufacturing processes.
    Q What is the particle size of NTR-606 and how does it affect performance?
    NTR-606 has a controlled particle size of 0.28 microns, which is optimized for maximum light scattering and hiding power. This precise particle size distribution ensures uniform dispersion in formulations, contributes to smooth processing on automated production lines, and delivers consistent color development and opacity in the final coated or molded product.
