Product Details
Comprehensive information about our iron oxide pigments including specifications, applications, advantages, and more
Cement Coloring Iron Oxide Powders
High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
Building a More Colorful World
Deqing Demi Pigment Technology Co., Ltd. is a foundational supplier to the global cement industry. We provide the "Permanent Pigments" that transform grey infrastructure into vibrant architectural landmarks. Our cement-grade powders are recognized for their exceptional tinting strength and ease of use in both dry-mix and wet-batching environments. We partner with cement manufacturers and construction firms to ensure that every pour results in a uniform, durable, and aesthetically pleasing finish.
Cement Coloring Usage Areas
- Cement Tiles & Shingles: Durable red, charcoal, and brown roofing solutions.
- Self-Leveling Screeds: Uniformly colored interior industrial flooring.
- Pre-cast Masonry: Consistent color for bricks, blocks, and lintels.
- Mortar & Grout: High-strength colorants for architectural jointing.
Cement Grade Technical Specs
| Metric | Value | Standard |
| Alkali Resistance | Grade 5 (Excellent) | DIN 54001 |
| Water Soluble Salts | Max 0.3% | ISO 787-3 |
| Tinting Strength | 100% ± 3% | ISO 787-24 |
| pH Stability | Range 4 - 13 | Internal Method |
| Oil Absorption | 18 - 25 g/100g | ISO 787-5 |
Core Advantages
- Structural Integrity: No negative impact on the 28-day compressive strength of cement.
- Efflorescence Resistance: Low soluble salt content helps prevent white lime blooming.
- UV Immunity: Color will not fade under direct sunlight or harsh weather.
- High Dispersion: Rapidly colors the cement paste without leaving streaks or "specks."
Q: Will the color wash off the cement surface?
A: No, these are integral pigments that color the entire thickness of the material, not just a surface coating.
Q: Does it affect the setting time?
A: At recommended dosages (<10%), our high-purity oxides have no measurable effect on setting or curing times.
Ready-Mix Integration Support
We provide "Slurry Conversion" guides, helping large-scale cement plants transition from dry powder to liquid-dosing systems for better accuracy and dust control.
Custom Color Matching: We can replicate the specific "Sand" or "Slate" tones required for regional architectural styles using our proprietary blending technology.
The Science of Cementitious Dispersion
In cement coloring, we focus on the "Electrostatic Interaction" between the pigment and the cement particles. During the mixing phase, our pigments are engineered to have a surface charge that prevents agglomeration. This ensures that the iron oxide particles coat the individual cement grains evenly, maximizing the color efficiency and preventing "color-starvation" in high-water-ratio mixes.
