Core Characteristics and Application Value
The wide application of iron oxide red stems from its unique advantages as an inorganic pigment, providing a durable guarantee for “red-based” modern industries:
Exceptional durability: Excellent light resistance, weather resistance, and high-temperature resistance. The color remains stable even under long-term exposure to the sun, wind, rain, and high temperatures, and it is not prone to flaking or fading, with a much longer service life than organic pigments.
Outstanding physical properties: It has extremely high covering power and excellent coloring ability. A small amount of addition can achieve a full and uniform red effect, and it can effectively shield ultraviolet rays to protect the substrate.
Excellent chemical stability: Resistant to acids, alkalis, and solvents. The color remains stable in complex chemical environments and is suitable for demanding industrial environments. Safety and Environmental Protection: Non-toxic and odorless, safe for both human body and the environment, in compliance with various environmental protection regulations (such as EU REACH), it is an ideal alternative to some heavy metal pigments (such as lead chromate).
