TINOX CR-1120 Rutile Titanium Dioxide

I. Chloride Process Advantages

The chloride manufacturing process is key to CR-1120's premium quality:

• Advanced Particle Size Control: Enables precise optimization of TiO_{2 particle size and distribution. This directly enhances optical properties like opacity and gloss.}
• Higher Purity: Typically results in a purer TiO₂ crystal compared to alternative processes, contributing to brighter whites and cleaner color tones. This is reflected in its high TiO₂ content (>93.0%).
• Enhanced Whiteness & Brightness: The purity and controlled particle characteristics translate to superior powder brightness (L* ≥ 98.0) and low yellowness (b* ≤ 2.0), providing a brilliant white base.
• Bluish Undertone: The specific characteristics imparted by the chloride process contribute to the pigment's desirable bluish undertone, enhancing perceived whiteness in formulations.

II. Key Performance Characteristics

1. Exceptional Opacity (Hiding Power) & Tinting Strength

• Strong Hiding Power: Provides excellent coverage, reducing the amount of pigment required to achieve opacity in paints, coatings, and plastics. This improves formulation efficiency.
• High Tinting Strength: Delivers intense color development when used with colorants. Quantified by a Reynolds tinting strength of ≥ 1900 in pigmented systems.
• Optical Efficiency: The chloride process's optimized rutile crystals (≥99.5% rutile content) and particle size maximize light scattering efficiency, the core mechanism behind its opacity and tinting strength.

2. Superior Durability & Weathering Resistance

• Strong Durability: Formulated to withstand environmental stresses critical for long-lasting performance.
• Advanced Surface Treatment: Treated with Aluminium (Al), Zirconium (Zr), and Organic compounds. This surface treatment stabilizes the pigment particles, enhances dispersion, and crucially provides resistance against degradation caused by UV light, moisture, and atmospheric pollutants.
• Compliance: Meets relevant industry standards for durability in demanding applications (e.g., ASTM D-476 Types II, III, IV, V; GB/T1706 R2).

3. Excellent & Long-Lasting Whiteness

• High Initial Whiteness: Powder brightness L* ≥ 98.0 ensures a brilliantly white starting point.
• Neutral Tone: Low yellowness (b* ≤ 2.0) provides a clean, neutral white appearance.
• Resistance to Yellowing/Degradation: The combination of the chloride process rutile crystal structure, high purity, and the specialized Al/Zr/Organic surface treatment provides inherent resistance to photocatalytic activity. This minimizes chalking and helps maintain the pigment's whiteness and gloss over extended periods of exposure to sunlight and weather, especially important in exterior applications.

4. Additional Performance Enhancers

• Excellent Gloss Development: Contributes to high-gloss finishes in coatings and inks.
• Good Dispersibility: Achieves ≥ 6.5 on the Hegman scale, facilitating easier incorporation into various binders and reducing processing time/energy.
• Low Oil Absorption (≤18 g/100g): Allows for higher pigment loading in formulations while maintaining good rheological properties (flow).

TINOX is a titanium dioxide supplier originated from Dusseldorf Germany, with the manufacturing cost up-rising in EU. TINOX has to shift the manufacturing to China. So since 2019, TINOX gradually put the investment into China mainland both technically and capitally. Investing the technology and equipment into China enpower TINOX products with better economical value without compromising on quality.

Now, with years operation in China mainland, Tinox China is not only fulfill its responsibility as a Tinox company, but also enable Tinox providing better services on outsourcing, timely delivery.
