Universal Rutile Titanium Dioxide HTR-628 for Coating, Paint, and Plastic Applications
Product Overview
Yunnan Dahutong HTR-628 Rutile Titanium Dioxide redefines industrial pigment performance through cutting-edge inorganic-organic hybrid engineering. This zirconium oxide (ZrO₂) and aluminum oxide (Al₂O₃) composite-coated pigment, further enhanced by proprietary organic surface modification, sets new benchmarks in whiteness, dispersibility, and environmental adaptability. With TiO₂ content ≥93% and rutile crystallinity ≥98%, HTR-628 delivers unmatched opacity (Reynolds number ≥1900) and universal compatibility across water-based/oil-based systems, making it the ideal choice for decorative paints, powder coatings, coil coatings, plastics, inks, and specialty applications.
Certified to ISO 9001 standards and produced under REACH compliance, this pigment combines ≥94.5% brightness (HunterLab) with oil absorption ≤20 g/100g, enabling 15–20% formulation cost reductions versus conventional TiO₂ grades. Available in spot purchases or bulk contracts, HTR-628 supports global supply chains with strict quality consistency (45μm residue ≤0.02%).
