Frequently Asked Questions
Q1: What are the primary benefits of the blue undertone?
The blue undertone provides a cleaner, brighter white appearance by neutralizing natural yellow tints in polymers and coatings.
Q2: Is this grade suitable for high-temperature processing?
Yes, it is specifically designed with high thermal stability, making it ideal for demanding masterbatch and powder coating applications.
Q3: How does the surface treatment affect performance?
The ZrO2 and Al2O3 inorganic treatments combined with organic treatment enhance dispersibility and weather resistance (R2 classification).
Q4: What is the oil absorption rate of this product?
The oil absorption is measured at 19g/100g, which helps in maintaining optimal viscosity during the manufacturing process.
Q5: What is the purity level of this TiO2 grade?
This grade contains a minimum of 94% TiO2 content according to ISO 591-1 standards.
Q6: Can it be used in outdoor powder coatings?
Yes, as an R2 classified Rutile TiO2, it provides the necessary durability and opacity required for high-performance coating systems.
