Blue Iron Oxide Pigments

Broadening the Inorganic Palette

Deqing Demi Pigment Technology Co., Ltd. is committed to providing a full spectrum of stable mineral colors. We recognize that achieving a durable blue in inorganic systems is a technical challenge. Our blue iron oxide series is engineered to provide the richness of blue with the legendary stability of an oxide. We provide the "Permanent Blue" solutions that allow architects and manufacturers to design with confidence, knowing their colors will withstand the test of time and nature.

Blue Oxide Usage Areas

• Colored Mortar: Permanent blue joints for brickwork and masonry.
• Roofing Tiles: UV-stable blue for concrete and ceramic tiles.
• Industrial Paints: Weather-resistant blue for outdoor equipment.
• Plastic Compounding: Stable blue for outdoor bins and crates.

Blue Oxide Technical Specs

Core Advantages

• Non-Fading: Far superior to organic blues in direct sunlight.
• Cement Compatible: Will not react with the lime in cementitious systems.
• Environmentally Safe: Heavy-metal free and non-toxic for safe handling.
• Rich Saturation: Provides deep, earthy blue tones that look natural.

• Q: Is this blue safe for swimming pool concrete?

  A: Yes, it is highly resistant to both water and the chemicals typically used in pool maintenance.

• Q: Does it mix well with white cement?

  A: Excellent. Mixing with white cement yields bright, sky-blue shades with great uniformity.

Specialized Color Blending

We offer "Blue Shade Matching," where we can adjust the undertone of the blue oxide from a "Greenish-Blue" to a "Royal-Blue" to match your project needs.

Sample Protyping: We provide 1kg samples for concrete trial pours to ensure the cured color meets your architectural specifications.

The Science of Hybrid Colorants

In blue iron oxide, the color is achieved through "Inter-Element Synergism." By co-precipitating iron salts with blue-inducing mineral agents, we create a hybrid crystal. This structure ensures that the blue component is physically protected by the iron oxide matrix. This prevents "Hydrolysis"—a common failure in blue dyes where water breaks down the color molecule. The result is a pigment where the color is structurally locked, providing the "Oxide Durability" alongside a vibrant blue spectrum.
