Xianghai Brand Titanium Dioxide Cr-6618 - High Coverage and Brightness for Paint and Coatings

Product Overview‌

Xianghai CR-6618 is a ‌high-performance rutile titanium dioxide pigment‌ manufactured via the advanced ‌chlorination process‌, featuring dual surface modification with ‌zirconium-aluminum inorganic coatings‌ and ‌organic treatment agents‌. Engineered for universal compatibility, it delivers exceptional optical properties, dispersion efficiency, and durability across coatings, plastics, inks, and specialty applications. With TiO₂ purity exceeding 94.65% and industry-leading iron content control (17 ppm), CR-6618 sets benchmarks in whiteness (L* ≥97.00), tinting strength (112% vs. industry standard), and process stability. Its optimized particle size distribution (D50: 0.25–0.35 μm) ensures maximum light scattering efficiency, achieving opacity and gloss balance unmatched by conventional sulfate-process alternatives.

‌Technical Specifications & Performance Data‌

‌Advanced Surface Modification Technology‌

‌1. Zirconium-Aluminum Inorganic Coating‌

• ‌Durability Enhancement‌:
  • Forms a dense 8–12 nm oxide layer, improving UV resistance (QUV-B 2,000h ΔE <1.5).
  • Reduces photocatalytic activity by 60% compared to uncoated grades.
• ‌pH Stability‌: Neutral coating (pH 7.47) minimizes resin compatibility issues in both acidic (epoxy) and alkaline (latex) systems.

‌2. Organic Surface Treatment‌

• ‌Dispersion Optimization‌:
  • Lowers oil absorption to 17 g/100g, enabling high-PVC formulations (up to 45%) without compromising flow.
  • Achieves 10 μm dispersion fineness, reducing milling time by 30–50%.
• ‌Hydrophobic Control‌: Balanced HLB value ensures stability in solvent-borne (polar/non-polar) and waterborne systems.
