After surface modification by Aluminum inorganic coating and organic treatment agent. It features an average particle size distribution, bluish undertone, good dispersion, low volatility, low oil absorption, excellent yellowing resistance, and superior process rheological properties.
CR-758 Shandong Xianghai Chloride-Process Titanium Dioxide is a high-performance rutile TiO₂ pigment produced via the chloride route. Widely recognized for its low impurity levels, exceptional whiteness, and stable undertone, CR-758 is specifically engineered for demanding coating and plastic applications. It delivers outstanding opacity (hiding power) and high tinting strength, significantly enhancing the brightness and gloss of finished products.
To ensure optimal processing, CR-758 undergoes advanced surface engineering, including inorganic coatings (silica/alumina) and organic treatments. These modifications improve wetting, reduce oil absorption, and stabilize rheology, minimizing agglomeration during high-speed mixing. This results in smoother leveling, better resistance to floating/flooding, and consistent batch-to-batch quality. Its inherent rutile structure provides robust weather, heat, and chemical resistance, protecting against chalking and discoloration in harsh environments.

Frequently Asked Questions
What makes CR-758 different from sulfate-process TiO2?
CR-758 is produced via the chloride process, which typically results in a tighter particle size distribution, higher purity, and better brightness compared to traditional sulfate-process grades.
How does the Al2O3 surface treatment benefit the product?
The Aluminum inorganic coating improves the pigment's dispersibility in various media and enhances its weather resistance and durability in outdoor applications.
Is CR-758 suitable for outdoor plastic products?
Yes, its rutile structure and specialized surface treatment provide excellent resistance to UV radiation, heat, and chemical exposure, preventing yellowing and chalking.
What is the significance of the "bluish undertone"?
A bluish undertone helps to counteract the natural yellowness of resins, resulting in a cleaner, brighter, and more visually appealing white in the final product.
How should CR-758 be stored to maintain quality?
It should be stored in a cool, dry, and ventilated area. Keep the packaging tightly sealed to protect the powder from moisture, direct sunlight, and extreme heat.
Can CR-758 be used in solvent-based inks?
Absolutely. Its low oil absorption and excellent rheological properties make it highly compatible with solvent-based ink systems, ensuring high gloss and opacity.
