Industrial Iron Oxide Colorants
High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
The Industrial Standard in Color Performance
Deqing Demi Pigment Technology Co., Ltd. is the trusted partner for the world's largest industrial manufacturers. We understand that in industrial production, downtime is the enemy; therefore, we provide colorants with "Absolute Batch Reliability." Our industrial series is designed for "Set-and-Forget" performance. Whether you are coloring millions of concrete blocks or thousands of liters of industrial primer, our pigments ensure your production line runs smoothly and your color remains perfectly on-spec.
Industrial Colorant Usage Areas
- Automated Concrete Plants: High-volume coloring for blocks, pipes, and pavers.
- Industrial Primers: Corrosion-resistant colorants for steel and machinery.
- Bulk Compounding: Efficient coloring for large-scale plastic production.
- Textile Auxiliaries: Durable mineral colorants for heavy-duty industrial fabrics.
Industrial Grade Technical Specs
| Metric | Value | Standard |
| Tinting Strength | 95% - 105% | ISO 787-24 |
| Moisture Content | Max 1.0% | ISO 787-2 |
| pH Value | 5.0 - 8.0 | ISO 787-9 |
| Specific Resistance | Min 1500 Ω⋅cm | ISO 787-14 |
| Hegman Fineness | 4.0 - 6.0 | ISO 1524 |
Industrial Efficiency Features
- High Throughput: Low oil absorption allows for higher pigment loading in masterbatches.
- Dust-Reduced Grades: Enhances worker safety and maintains a clean factory environment.
- Automated Compatibility: Free-flowing powders designed for screw-feeders and silos.
- Cost Optimization: High strength means lower material costs per finished unit.
Q: Do these pigments affect the setting time of industrial concrete?
A: No, our industrial grade is washed to remove soluble salts that can interfere with cement hydration.
Q: Can they be shipped in bulk?
A: Yes, we specialize in bulk-bag (ton-bag) logistics and can provide silo-filling solutions for large industrial consumers.
Production Line Integration
We provide "Custom Slurry" services, delivering our pigments in pre-dispersed liquid form to integrate directly into your liquid-dosing industrial lines.
On-Site Technical Support: Our engineers can visit your factory to help optimize your mixing times and pigment ratios, ensuring maximum color development and cost savings.
The Science of Dispersion Kinetics
In industrial applications, we focus on the "Rate of Color Development." We measure the torque required in the mixer to reach full tinting strength. By applying specialized "Dispersing Aids" during the milling process, we ensure that our industrial colorants break down from agglomerates into primary particles in seconds. This ensures that even in short-cycle industrial mixing, the color is uniform and the "Delta E" is minimized across the entire production shift.
