Functional Coloring Mineral Powders
High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
Engineering Intelligence into Every Particle
Deqing Demi Pigment Technology Co., Ltd. is a pioneer in functional mineral science. We recognize that in the 21st century, color is not enough—materials must do more. Our functional series is developed for high-tech industries that require "Smart Pigments." We provide the "Functional Foundation" that allows our clients to create smarter, more durable, and more efficient products, from heat-reflective roofs to magnetically detectable packaging.
Functional Powder Usage Areas
- UV Blockers: Protecting polymers and thin films from solar radiation.
- Magnetic Pigments: Used in detectable plastics for the food and pharma industries.
- Anti-Corrosive Primers: Active rust inhibition in industrial steel coatings.
- Heat Reflectors: "Cool Pigment" technology for energy-efficient buildings.
Functional Technical Specs
| Property | Value | Function |
| UV Absorption | 98% (200-400nm) | Polymer Protection |
| Magnetic Induction | Customizable | Detection/Sorting |
| Specific Surface Area | 15 - 35 m²/g | Adhesion/Reactivity |
| Chloride Content | Max 0.01% | Corrosion Control |
| Resistivity | High | Electrical Insulation |
Performance Features
- Multi-Tasking: Provides vibrant color while enhancing material life.
- Lattice Stability: Maintains functional properties under extreme heat and pressure.
- Total Inactivity: Does not interfere with the chemical curing of advanced resins.
- Safety Focused: Inert minerals that replace more hazardous chemical additives.
Q: Can these powders help reduce cooling costs?
A: Yes, our "Cool Red" and "Cool Black" functional powders reflect Near-Infrared (NIR) light, keeping surfaces significantly cooler.
Q: Are the magnetic grades safe?
A: Yes, they are based on stable magnetite (Fe3O4) and are non-toxic for use in food-processing equipment.
R&D Collaboration Services
We offer "Joint Innovation Projects," working with your engineering team to develop a pigment with a specific functional "Fingerprint."
Custom Functional Blends: We can combine different mineral powders to achieve a balance of UV protection, color, and magnetic detection.
The Science of Wavefront Manipulation
Functional mineral science is based on "Electronic Transition Tuning." By adjusting the "Band Gap" of the iron oxide crystal through controlled impurities or doping, we can dictate which wavelengths of energy the pigment interacts with. This scientific manipulation allows us to design a pigment that absorbs harmful UV (300nm) but reflects thermal IR (above 700nm). This "Spectral Engineering" is what transforms a simple colorant into a high-performance functional material.
