THR-218 Sulfate Process Rutile Titanium Dioxide with ZrO₂ + Al₂O₃ Coating for High Whiteness ≥95.0 and Low Oil Absorption ≤19 g/100g

THR-218 Sulfate Process Rutile Titanium Dioxide
Technical Data Sheet & Certificate of Analysis

1. Product Introduction
THR-218 is multi-purpose rutile titanium dioxide manufactured by sulfate process with zirconium-aluminum composite surface modification. Strict production control realizes uniform particle size and narrow particle distribution. This pigment delivers outstanding whiteness, excellent dispersibility, low oil absorption and high tinting strength. It is a universal pigment widely applicable to architectural & industrial coatings, printing inks, papermaking, plastics, artificial leather and other industries.
2. Typical Performance Index

3. Core Product Advantages
1. Zirconia and alumina double coating provides certain outdoor weather resistance, inhibiting UV aging and coating film chalking.
2. Narrow particle size distribution brings high whiteness and clean tone, improving surface brightness of finished coatings and plastic products.
3. Low oil absorption value reduces system viscosity during grinding, saves solvent and plasticizer consumption, improves production efficiency.
4. Superior wetting & dispersibility, no agglomeration in waterborne, solvent and plastic resin systems, shortens sand mill grinding time.
5. High tinting strength reduces pigment dosage in formulas, effectively lowering overall production cost.
6. Multi-system compatibility, meets the production demands of coatings, ink, paper, plastic and leather industries simultaneously.
4. Recommended Application Fields
• Indoor & exterior architectural paints, general industrial protective coatings
• Water-based and solvent-based printing inks
• Papermaking filling and coating pigments
• All kinds of plastic products, color masterbatch, artificial leather materials
5. Packaging Specification
• Standard small package: 25kg paper-plastic composite moisture-proof bag
• Bulk ton packaging: 500kg / 1000kg flexible IBC jumbo bag
6. Storage & Operation Safety Guidance
Storage Requirements
Store in dry, cool and ventilated warehouse, avoid damp environment, high temperature and direct sunlight. Keep packaging tightly sealed after opening to prevent powder agglomeration caused by moisture absorption. Adopt first-in first-out inventory management.
Operation Safety
Wear dust masks, protective gloves and safety goggles during feeding and mixing operations to avoid long-term inhalation of pigment dust. In case of eye contact, rinse with a large amount of clean water immediately; clean skin thoroughly with soap after direct contact with powder.
7. Quality Statement
All typical performance data listed in this document are factory lab test reference values, not binding product acceptance standards. Actual dispersion, gloss and hiding power will be affected by customer formula, grinding equipment and construction process. Small batch trial test before mass production is strongly recommended to verify product adaptability.
