Frequently Asked Questions
Q: Which iron oxide color is most commonly used in construction?
Iron Oxide Red is the most widely used, accounting for approximately 50% of total iron oxide pigment consumption, followed by Yellow and Black for concrete and bricks.
Q: Are these pigments safe for use in cosmetic products?
Yes, iron oxide pigments are non-toxic and naturally derived, making them suitable for use as cosmetic pigments, provided they meet specific purity grades.
Q: How does iron oxide perform in high-temperature environments?
Our iron oxide pigments are exceptionally heat-stable, maintaining their color integrity even at temperatures up to 300 ℃ without changing hue.
Q: Can iron oxide be used in water-based paints?
Absolutely. They are widely used in water-borne internal and external wall coatings due to their excellent dispersion and water insolubility.
Q: What is the difference between synthetic and natural iron oxide?
Synthetic iron oxide, produced via chemical synthesis, offers higher purity, more uniform particle size, and a wider range of consistent colors compared to natural sources.
Q: Does the pigment affect the structural integrity of concrete?
No, iron oxide pigments are compatible with cement. In fact, they can improve durability by increasing resistance to UV rays and environmental fluctuations.
