What Is Iron Oxide Red? Properties, Color Performance & Industrial Application Guide
Introduction
Iron Oxide Red, also known as red iron oxide, chemical formula Fe₂O₃, is one of the most widely used inorganic color pigments globally. Featured with outstanding weather resistance, UV resistance, chemical stability and competitive price, it has replaced many organic pigments in numerous industrial coloring fields.
Manufacturers supply various model numbers including 110, 120, 130, 180 iron oxide red with different red tones, particle sizes and dispersibility. Buyers need to select suitable models according to target products.

Main Industrial Applications
1. Construction & Concrete Industry
Iron oxide red is the primary pigment for colored asphalt, cement tiles, concrete pavers, artificial stone and mortar. It maintains stable color after long-term outdoor exposure.
2. Coatings & Paints
Applied in anti-rust paint, architectural paint, industrial coatings, water-based and solvent-based paints. It not only provides red color but also delivers certain anti-corrosion effects.
3. Rubber & Plastic Coloring
Suitable for PVC, PE, rubber products, plastic pipe, floor mat coloration. Good dispersion ensures uniform color without fading.
4. Ceramic & Glaze Pigment
Used for ceramic body coloring, tile glazes, pottery products. It keeps color stable under medium and high temperature firing.
5. Paper, Ink & Cosmetic Raw Materials
Food-grade and cosmetic grade iron oxide red can be used for cosmetic coloring; industrial grade applies to printing ink and decorative paper.
Grade & Model Selection Guide
- Building materials / concrete: Iron Oxide Red 110, 120, cost-effective standard models
- Coating and paint industry: Red 130 with better dispersibility
- Plastic & rubber products: Red 180, fine particle size for smooth surface
- Ceramic production: High temperature resistant iron oxide red with low impurity
Storage & Handling Recommendations
- Store in sealed bags, dry and ventilated warehouse, avoid moisture agglomeration.
- Prevent mixing with strong oxidants and strong acids.
- Wear dust masks during operation to avoid long-term inhalation of dust.
- No special hazardous goods restrictions for regular sea transportation. SDS documents are required.
FAQ
Q1: What is the difference between synthetic iron oxide red and natural iron oxide red?
Synthetic iron oxide red has purer color, uniform particle size and stable quality, which dominates industrial use. Natural iron oxide red has more impurities, unstable tone and is less used in high-end products.
Q2: Will iron oxide red fade outdoors?
High-quality iron oxide red boasts superior weather resistance. It hardly fades under long-term sunlight exposure, much better than most organic red pigments.
Q3: Can customized color tone iron oxide red be provided?
Suppliers can offer different shades from yellowish red to purplish red by adjusting production process and particle size.
