Pigments Powder for Road Markings
High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
Strategic Partner for Traffic Safety Infrastructure
Deqing Demi Pigment Technology Co., Ltd. is a major supplier of pigments for the road marking industry worldwide. We provide the high-chroma yellows and reds, and high-opacity blacks required for lane markings, pedestrian crossings, and safety zones. Our pigments are manufactured to meet the strict color coordinate requirements set by international transport authorities. We focus on providing materials that offer a long service life, reducing the need for frequent re-painting and ensuring consistent road safety.
Road Marking Application Sectors
- Thermoplastic Markings: Heat-stable pigments for hot-applied road lines.
- Cold-Plastic Markings: Fast-curing pigments for high-traffic intersections.
- Solvent/Water-borne Paints: Durable coloring for temporary and permanent road markings.
- Airport Runways: High-performance pigments for critical aviation markings.
Road Marking Technical Data
| Property | Standard Value | Standard |

| Heat Stability (Thermoplastic) | 200 - 240 | Degrees Celsius |
| Oil Absorption | 15 - 25 | g/100g |
| Specific Gravity | 4.0 - 5.0 | g/cm3 |
| Color Coordinates | Compliant with AASHTO/EN | CIE 1931 |
Attributes for Infrastructure Safety
- Exceptional Weathering: Resistance to rain, snow, salt, and intense UV radiation.
- Anti-Skid Compatibility: Does not affect the friction coefficient of the marking material.
- Rapid Integration: Easily mixed into thermoplastic melts at high temperatures.
- Permanent Color: Inorganic nature ensures no fading even after millions of tire passes.
Q: Does the yellow pigment contain Lead Chromate?
A: No, we provide Lead-free Iron Oxide and Organic/Inorganic hybrid yellows that meet modern environmental safety standards for roads.
Q: How does it perform with glass beads?
A: Our pigments provide a high-contrast background that enhances the retro-reflectivity of the embedded glass beads at night.
Traffic Color Compliance Services
We provide batch-specific CIE color coordinate reports (x,y,Y) to ensure our pigments meet the "Daytime Color" and "Nighttime Color" standards required by highway agencies.
Bulk Logistics for Projects: For large-scale infrastructure projects, we offer customized packaging and inventory management to ensure a steady supply for continuous road-painting operations.
The Science of Visibility and Contrast
Road safety color science is based on "Luminance Factor" (Y) and "Chromaticity." We use spectrophotometers to ensure that our yellow pigments fall within the specified "Safety Box" on the CIE chromaticity diagram. By maximizing the Y value, we ensure that the markings provide the highest possible contrast against dark asphalt, even in rain or fog. We also monitor the "Spectral Reflectance" to ensure that the pigments do not absorb the light intended for retro-reflection back to the driver's eyes.
