Product Description
TINOX TPW-716 Hybrid Pigment White Overview
TINOX TPW-716 is an advanced hybrid pigment based on rutile-type TiO₂, engineered specifically for high-performance paint and coating applications. This premium pigment combines TiO₂ components with ultra-fine functional fillers to enhance light scattering efficiency while reducing TiO₂ consumption without compromising optical performance.
Performance Advantages
- Superior optical properties with brightness L* ≥ 96.0 and bluish undertone
- Excellent gloss development for enhanced surface reflectivity and stability
- Strong hiding power with outstanding coverage and reduced pigment loading
- Enhanced durability with improved abrasion resistance and weather resistance
- Excellent dispersion with Hegman ≥ 6.5 for easy incorporation
- Environmental benefits with lower CO₂ emissions per unit

Processing Instructions
- Add water, dispersing agent, and wetting agent to mixing vessel
- Slowly add TINOX TPW-716 under moderate agitation (800-1000 rpm)
- Increase agitation speed to 1500-2000 rpm for 15-20 minutes until Hegman fineness ≥6.5 is achieved
- Reduce speed and slowly add acrylic emulsion
- Add coalescing agent, defoamer, rheology modifier, and preservative
- Adjust pH to 7.5-8.5 with ammonia solution
- Add remaining water to achieve desired viscosity
- Filter and package
Expected Performance
- Whiteness Index: ≥96.5
- Gloss (60°): ≥85 GU
- Contrast Ratio: ≥0.98
- Yellowness Index:
- PVC: ~25%
