Formulazione di precisione: la guida definitiva al biossido di titanio rutilo cinese ad alte prestazioni per rivestimenti esterni e interni.

Introduction: In the competitive world of architectural and industrial coatings, raw material selection is the foundation of quality. For paint manufacturers, the goal is clear: achieve maximum durability, exceptional opacity, and brilliant whiteness while maintaining formulation efficiency.

A RawChemicalMart, we have curated a portfolio of the premier Titanium Dioxide grades from China’s top-tier manufacturers. This guide focuses on the technical specifications and performance characteristics of the market’s leading Rutile grades, designed to meet the rigorous demands of modern exterior and interior coating systems.

1. The Pinnacle of Weatherability (Chloride Process)

For applications where long-term outdoor durability and gloss retention are non-negotiable, the Chloride process remains the gold standard.

Product: LB Group | BLR-895

• Production Process: Chloride (氯化法)
• Surface Treatment: Allumina, Zirconia
• Description: BLR-895 is a coating-grade rutile titanium dioxide pigment renowned for its exceptional dispersion and high opacity. Produced via the Chloride process, it possesses a tighter particle size distribution, resulting in a cleaner hue and higher gloss potential compared to standard sulfate grades.
• Key Performance Features:
  • Extreme Weather Resistance: Excellent resistance to chalking and yellowing under high UV exposure.
  • High Gloss: Delivers a mirror-like finish in high-end enamels.
  • Fast Dispersion: Wets out quickly, reducing energy consumption during production.
• Ideal Applications: High-end exterior architectural coatings, automotive OEM coatings, and coil coatings.

2. The Specialists: High Opacity & Whiteness

When one-coat coverage and pure whiteness are the priority, specific Sulfate grades with optimized Zirconium treatments are the preferred choice.

Product: Doguide | SR-2377

• Production Process: Sulfate (硫酸法)
• Surface Treatment: Zirconia, Alumina, Organic treatment
• Description: Manufactured by Shandong Doguide, SR-2377 is engineered specifically for “Hiding Power.” Its unique surface treatment technology optimizes light scattering efficiency, making it one of the most opaque grades available in the domestic market.
• Key Performance Features:
  • Maximum Opacity: Provides superior coverage over dark substrates.
  • Blue-White Undertone: Offers a crisp, clean visual appearance.
  • Low Oil Absorption: Allows for higher pigment loading in formulations.
• Ideal Applications: Premium interior emulsions, high-solid paints, and powder coatings.

Product: CNNC Huaruan | R-216

• Production Process: Sulfate (硫酸法)
• Surface Treatment: Alumina, Silica, Special Organic treatment
• Description: R-216 is widely recognized for its excellent pigment performance and distinct color characteristics. It is a benchmark product for formulations requiring a balanced combination of whiteness and weather stability.
• Key Performance Features:
  • Strong Blue Undertone: Effectively counteracts yellowing in resins.
  • Versatility: Performs consistently across both solvent-based and water-borne systems.
• Ideal Applications: Interior and exterior wall coatings, masterbatches, and profile extrusion.

3. The Industry Standards: Durability & Universality

These grades represent the backbone of the coatings industry—reliable, stable, and versatile enough for a wide range of applications.

Product: Pangang (Vanadium & Titanium) | R-298

• Production Process: Sulfate (硫酸法)
• Surface Treatment: Zirconia, Alumina, Organic treatment
• Description: Sourced from the Panzhihua region, known for its high-grade titanium ore, R-298 is a multi-purpose rutile grade. It distinguishes itself with moderate-to-high particle size allowing for robust weather resistance in harsh industrial environments.
• Key Performance Features:
  • Structural Stability: High tint-reducing power and ease of dispersion.
  • Industrial Toughness: Excellent performance in maintaining film integrity in outdoor industrial settings.
• Ideal Applications: Industrial anti-corrosion paints, exterior architectural coatings, and road marking paints.

Product: LB Group | R-996

• Production Process: Sulfate (硫酸法)
• Surface Treatment: Zirconia, Alumina
• Description: R-996 is perhaps the most widely recognized universal grade in the global market. Its primary strength lies in its batch-to-batch consistency and adaptability.
• Key Performance Features:
  • Universal Compatibility: Works seamlessly in solvent, water, and powder systems.
  • High Durability: Treated with Zirconia and Alumina to ensure longevity.
  • Processing Ease: Known for excellent dispersion properties, improving production efficiency.
• Ideal Applications: General purpose interior/exterior paints, powder coatings, and inks.

4. The Value-Optimized Performer

For formulations that demand a strong balance of performance and cost-effectiveness, this grade offers a compelling solution.

Product: Jinhai (Jinzhou) | R-6618

• Production Process: Sulfate (硫酸法)
• Surface Treatment: Allumina, Zirconia
• Description: R-6618 is a high-performance rutile titanium dioxide designed to deliver excellent optical properties and good durability at a competitive price point. It is a popular choice for manufacturers seeking to optimize their formulations for both quality and cost.
• Key Performance Features:
  • Excellent Gloss & Brightness: Provides a bright finish in both interior and exterior applications.
  • Good Dispersion: Ensures ease of processing and stable performance in various systems.
  • Cost-Effective: Offers a favorable performance-to-price ratio for large-volume applications.
• Ideal Applications: Cost-optimized exterior and interior architectural paints, industrial coatings, and masterbatches.
