Inorganic Pigment Coloring Solutions

Your Full Spectrum Coloring Partner

Deqing Demi Pigment Technology Co., Ltd. is your single source for complete Inorganic Pigment Coloring Solutions. We offer not just individual colorants but an integrated system designed for predictable and reproducible color results across diverse manufacturing processes. Our expertise lies in advising clients on how to utilize the full color palette of iron oxides and composite pigments to achieve virtually any desired shade in their end products, while strictly adhering to performance specifications like low heavy metal content and high heat stability.

Diverse Manufacturing Segments

• Construction and Building Materials: From base colors to complex architectural tones.
• Coatings and Paints: Base pigments for tinting systems, industrial, and architectural coatings.
• Plastics and Rubber Compounding: Bulk coloring for masterbatches and direct compounding.
• Specialty Applications: Coloring for fertilizers, abrasives, and magnetic materials.

Integrated Portfolio Color Data (Example)

Systemic Coloring Benefits

• Full Palette Availability: Access to a complete range of highly compatible inorganic primary and secondary colors.
• Recipe Predictability: Provided CIELab data allows for precise computer-aided color matching and blending.
• Cross-Application Consistency: The ability to use similar pigment chemistry across product lines (e.g., matching a paver color to an exterior paint color).
• Simplified Sourcing: Single-source supply reduces logistical complexity and ensures uniform quality standards across all colors.

• Q: How can I ensure color consistency when buying different colors?

  A: We implement a rigorous CIELab tolerance system. Before shipment, every batch of every color is measured against a master standard. We guarantee that the color difference (ΔE) between batches will remain within tight, pre-defined limits.

• Q: Do you offer assistance in formulating custom colors?

  A: Yes, color formulation support is a core part of our service. Clients can send a physical sample or a target CIELab value, and our color lab will develop a precise recipe using our standard pigment portfolio, optimized for their specific matrix and process.

End-to-End Technical Color Support

We maintain a dedicated colorimetry lab equipped with advanced spectrophotometers and software for instantaneous color measurement and custom formulation. This ensures rapid turnaround for color matching requests.

Training and Consultation: We provide virtual and on-site technical training for client staff on best practices for pigment storage, dispersion, and color-blending techniques to maximize the efficiency of our coloring solutions in their factories.

CIELab and Spectral Curve Matching

Our entire portfolio is managed using the CIELab color space (L* for lightness, a* for red/green, b* for yellow/blue), which is the standard language of color science. Beyond the numeric CIELab values, we provide spectral reflectance curves. These curves are the "fingerprint" of the color and are crucial for metamerism control—ensuring that a matched color appears correct under different light sources (e.g., daylight vs. fluorescent). This advanced data management guarantees the highest level of color predictability for our clients.
