Product Details
Comprehensive information about our iron oxide pigments including specifications, applications, advantages, and more
Iron Oxide Yellow 313 (Precision Grade)
High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
Industry Leader in Yellow 313 Production
Deqing Demi Pigment Technology Co., Ltd. is a premier producer of the 313 series Iron Oxide Yellow. This grade is the result of decades of experience in the "Laux" and "Precipitation" processes. We focus on providing a yellow pigment that is free of soluble salts, making it ideal for high-performance coatings and cementitious products. Our 313 Yellow is recognized by global formulators for its reliability, ease of wetting, and consistent color development in both water-borne and solvent-borne systems.
Yellow 313 Application Sectors
- Architectural Paints: Base yellow for a wide range of interior and exterior wall colors.
- Concrete Products: High-purity yellow for pavers, tiles, and colored mortars.
- Plastic Masterbatch: UV-stable coloring for toys, furniture, and packaging.
- Industrial Coatings: Durable yellow for machinery and equipment finishes.

Yellow 313 Core Characteristics
- High Color Saturation: Provides a "clean" yellow that is not muddy or dull.
- Absolute Lightfastness: Rated 8 on the Blue Wool scale; will not fade in sunlight.
- Alkali Resistance: Completely stable in the high pH environment of fresh concrete.
- Good Dispersibility: Quickly reaches full color strength in standard mixing equipment.
Q: Is Yellow 313 heat stable?
A: Yellow 313 is stable up to 180∘C. For higher temperatures (powder coatings), we recommend our heat-stable yellow series or zinc ferrites.
Q: Does it contain organic dyes?
A: No, it is a 100% inorganic mineral pigment, ensuring total stability and permanence.
Precision Milling for Yellow 313
We offer Yellow 313 in various micronized grades to meet the specific "Hegman" requirements of high-end paint manufacturers, ensuring a smooth finish without surface defects.
Custom Packaging: For high-volume users, we provide bulk "toss-in" bags and automated dosing packaging to streamline production and minimize dust in the factory environment.
The Science of Yellow 313 Hue Angle
In color science, Yellow 313 is defined by its high "b*" (yellowness) and high "L*" (lightness) values. We monitor the "Hue Angle" (h) to ensure it remains in the optimal "Lemon-to-Mid Yellow" range. By controlling the length-to-width ratio of the acicular crystals, we optimize the light scattering to maximize the "Whiteness" and "Brightness" of the yellow. We provide spectral reflectance data to help formulators choose the right 313 grade to overcome the background color of their specific resin or cement.
