China Suppliers Factory CR-718 Rutile Titanium Dioxide Pigment - Chlorination Process, High Whiteness & Dispersion
Rutile titanium dioxide pigment produced by the chloride process. After surface modification by zirconium and aluminum inorganic coating and organic treatment agent, the particle size distribution is moderate, and it has excellent whiteness, dispersion, gloss, hiding power, weather resistance and other characteristics.
⚙️
Chloride-Process
Lower impurity content, higher whiteness and brightness, and a more stable undertone.
🛡️
Surface Treatment
Inorganic coatings (silica/alumina) and organic treatment to enhance wetting and dispersion.
✨
High Performance
Excellent opacity, high tinting strength, and superior weather resistance.
CR-718 Shandong Xianghai Chloride-Process Titanium Dioxide is a chloride-route rutile TiO₂ pigment, typically supplied as a white powder. In coatings and plastics, CR-718 provides excellent opacity (hiding power) and high tinting strength, helping improve whiteness, brightness, and gloss, while delivering a cleaner base color and improved batch-to-batch consistency.
Rutile TiO₂ also offers strong weatherability, heat resistance, and chemical resistance, helping reduce the risk of chalking, fading, or discoloration under outdoor exposure or harsh service conditions, thereby improving long-term durability.

Product Information
CR-718 is a chloride-process rutile titanium dioxide pigment marketed as a general-purpose grade for a wide range of color and coating applications. The product features a moderate particle size distribution and promotes a mix of excellent whiteness, dispersion, gloss, hiding power, and weather resistance. For many users, that combination is attractive because it suggests one pigment can cover multiple product lines while still giving a clean white and stable performance.
In coatings, strong hiding power and tinting strength help reduce the dosage needed to reach opacity targets. In inks, controlled dispersion helps minimize haze and supports predictable color development. In plastics and rubber, the surface treatment package improves compatibility with different polymer systems and reduces agglomeration.
Storage & Handling: For best results, pre-wet the pigment with the resin/solvent system, select a compatible dispersant, and use high-speed dispersion or milling. Store in a cool, dry place, keep containers tightly sealed, and protect from moisture and direct sunlight.
Frequently Asked Questions
What are the advantages of the chloride process used in CR-718?
The chloride process typically results in a pigment with lower impurity levels, higher whiteness, and a more consistent particle size compared to the sulfate process, ensuring superior brightness and stable performance.
How does the surface treatment benefit the final application?
CR-718 is treated with ZrO2 and Al2O3 alongside organic agents. This combination enhances dispersion, reduces oil absorption, and improves weatherability, making it easier to incorporate into various binder systems.
Is CR-718 suitable for outdoor use?
Yes, its rutile structure and specialized inorganic surface treatment provide strong weather resistance and chemical stability, effectively reducing chalking and discoloration in outdoor environments.
What is the recommended storage condition for this TiO2 pigment?
It should be stored in a cool, dry, and ventilated area. Keep the containers tightly sealed and protected from moisture, high heat, and direct sunlight to maintain its technical properties.
Can CR-718 be used in plastic masterbatches?
Absolutely. CR-718 is a general-purpose grade suitable for various plastics including PVC, PP, PE, and ABS, where it provides high opacity and excellent compatibility with polymer resins.
What is the rutile content of CR-718?
CR-718 maintains a high rutile content of ≥97.5%, which ensures maximum refractive index and superior hiding power for all colorant applications.
