Pigments for Industrial Coatings

Partnering in High-Performance Coatings

Deqing Demi Pigment Technology Co., Ltd. focuses on developing high-performance inorganic pigments that serve as critical components in industrial coating formulations. Our commitment is to produce materials that enhance the functional lifespan and aesthetic quality of protective surface treatments. We provide standard and micronized grades to accommodate various grinding methods and film thickness requirements inherent in automotive, marine, and protective coating applications.

Targeted Coating Systems

• Protective & Marine Coatings: Coatings for offshore structures, pipelines, and ship hulls requiring high corrosion resistance.
• Coil & Powder Coatings: High-heat stability grades for oven-cured systems.
• Automotive Finishes: Basecoat pigmentation requiring fine particle size and color consistency.
• Traffic & Floor Coatings: High-abrasion resistance formulations for road marking and epoxy flooring.

Dispersion and Stability Data

Functional Characteristics for Coatings

• Chemical Resistance: Inert to common solvents, acids, and alkalis encountered in industrial environments.
• Corrosion Inhibition Support: Acts as a stable barrier layer, enhancing the anti-corrosive properties of the coating formulation.
• High Compatibility: Surface properties facilitate easy integration into a wide variety of resin systems, including waterborne acrylics.
• Low Settling Rate: Fine particle size distribution aids suspension stability in liquid coatings over extended storage periods.

• Q: Are these pigments suitable for high-solids coatings?

  A: Yes, many of our grades, particularly the micronized series, are optimized for high-solids and low-VOC (Volatile Organic Compound) systems. Their high tinting strength minimizes the required volume, aiding in viscosity control.

• Q: How does particle size affect coating performance?

  A: Finer particle size (micronized grades) improves gloss, tinting strength, and ease of dispersion, making them suitable for thin-film applications like automotive finishes. Standard grades provide excellent hiding power and are typically used in thicker protective coatings.

Quality Assurance and Technical Partnership

Each batch undergoes rigorous quality control checks for color consistency (measured via ΔE values), oil absorption, and fineness of grind to ensure optimal performance in high-speed dispersion equipment.

Technical Collaboration: We offer specialized consultation to coating manufacturers, assisting in pigment selection and dosage optimization to achieve specific opacity and durability targets within their proprietary resin systems. This includes providing pre-dispersed samples for preliminary testing.

Color Measurement for Film Thickness

For coatings, color science must account for the final film thickness. Our CIELab data provides users with predictable color coordinates at specific target film thicknesses (e.g., 50 μm). We focus on maximizing the pigment's hiding power (opacity) to ensure cost-effective coverage. The spectral data helps predict the color match under different light sources, a critical factor for automotive and architectural applications where visual consistency is essential across various lighting conditions.
