Product Details
Comprehensive information about our iron oxide pigments including specifications, applications, advantages, and more
Concrete Surface Coloring Pigments
High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
The Art of the Finished Surface
Deqing Demi Pigment Technology Co., Ltd. provides the architectural finishing industry with the pigments needed to create high-impact "Designer" floors. We understand that the surface is where the beauty of concrete is truly seen. Our surface-grade pigments are the secret behind the world's most beautiful stamped and trowel-finished floors, offering a depth of color and a resistance to wear that makes them the preferred choice for high-end retail, hospitality, and residential projects.
Surface Coloring Usage Areas
- Color Hardeners: Dry-shake pigments for high-durability decorative floors.
- Concrete Stains: Fine-milled pigments for water-based or acid stains.
- Micro-Toppings: Vibrant coloring for ultra-thin decorative overlays.
- Polished Concrete: Integral coloring that maintains brilliance after grinding.
Surface Grade Technical Specs
| Metric | Value | Standard |
| Hiding Power | Excellent (Opaque) | Internal Method |
| Fineness (Hegman) | 6.0+ (Micro-milled) | ISO 1524 |
| UV Resistance | Grade 8 | Blue Wool Scale |
| Abrasion Impact | Zero Degradation | ASTM C944 |
| Oil Absorption | 15 - 20 g/100g | ISO 787-5 |
Performance Characteristics
- Saturated Hues: Provides a much darker, richer color than integral methods.
- Wear Protection: When mixed with hardeners, it significantly increases surface density.
- Pinhole-Free Finish: Ultra-fine particles ensure a smooth, professional surface.
- Fade Resistance: High-purity minerals are immune to the bleaching effects of sun.
Q: Is surface coloring more durable than paint?
A: Yes, significantly. Because it is worked into the wet concrete (dry-shake) or chemically bonded (stain), it will not peel or flake like a film-forming paint.
Q: Can I use this on an existing old concrete slab?
A: Yes, when used in a micro-topping or overlay system, our pigments can revitalize old concrete with a new, vibrant surface.
Architectural Sample Programs
We provide "Surface Swatches" showing various finishing techniques (broomed, stamped, polished) to help designers select the perfect surface pigment for their project.
Fine Grinding for Stains: For topical stain manufacturers, we provide "Micro-Sized" pigments that stay in suspension longer and penetrate deeper into the concrete pores.
The Science of Surface Reflection
In surface coloring, we focus on "Spectral Reflectance." [Image showing light reflecting off a pigmented concrete surface] Because these pigments are concentrated at the surface, we optimize their "Light Scattering" properties to maximize color saturation. By controlling the "Particle Shape Index," we can influence the matte or glossy appearance of the finished floor. Our pigments ensure that the light is reflected at the specific wavelengths needed to provide a "Rich and Deep" visual experience, regardless of the lighting conditions.
