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.
