Comprehensive information about our iron oxide pigments including specifications, applications, advantages, and more

Inorganic Pigments Powder for Construction Materials

High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.

Integrated Solutions for Architectural Durability

Deqing Demi Pigment Technology Co., Ltd. manufactures inorganic pigment powders designed to meet the rigorous physical requirements of the modern construction site. By focusing on the molecular stability of our pigments, we provide materials that assist builders and manufacturers in achieving predictable results. Our manufacturing facility utilizes advanced blending and milling equipment to ensure that every ton of powder delivered to a project site maintains the same color value and dispersion characteristics as the laboratory standard.

Structural and Decorative Construction Uses

  • Structural Concrete: Integral coloring of cast-in-place walls and foundations.
  • Architectural Precast: Coloring of decorative panels, stairs, and structural columns.
  • Masonry Units: Pigmentation for split-face blocks and decorative bricks.
  • Landscaping Materials: Colorants for retaining wall systems and garden borders.

Functional Attributes for Building Materials

  • Long-Term Stability: The inorganic structure resists breakdown from UV light and environmental acidity.
  • Matrix Compatibility: Does not negatively impact the compressive strength or setting time of cement-based materials.
  • High Hiding Power: Provides effective color saturation at low addition rates, minimizing the impact on the water-to-cement ratio.
  • Non-Migratory: Pigment particles remain fixed in the cured matrix, preventing surface bleeding or leaching.
  • Q: How does the pigment affect concrete strength?

    A: When used within the recommended dosage range of 3% to 6% by weight of cement, these inorganic pigments act as inert fillers and do not significantly alter the mechanical properties of the concrete.

  • Q: Can these powders be used in lime-based mortars?

    A: Yes, the chemical inertness of the iron oxide structure makes them suitable for lime and gypsum-based systems without risk of discoloration.

Manufacturing and Scalability

We operate large-scale production lines capable of supplying multi-ton orders with high batch-to-batch consistency. Our quality control department uses digital colorimetry to verify every production run against a master sample.

Custom Packaging: To support large construction projects, we offer customized packaging options including water-soluble bags for direct addition to mixers, reducing dust and improving dosage accuracy on-site.

Chromatic Engineering for Infrastructure

Color science in construction involves managing the "mass tone" of the pigment relative to the local sand and cement color. We provide CIELab data for our pigments in both grey and white cement bases. This allows architects to calculate the exact dosage required to achieve specific NCS or RAL color targets, accounting for the natural variance in construction aggregates. Our solutions focus on maintaining a Delta E variance of less than 1.0 between different manufacturing lots.
