Iron Oxide Red 120 is a common iron oxide pigment used in developing building materials, paints, rubber, asphalt, sports racetracks, paper, plastic and others. Offering excellent light and temperature resistance, Iron Oxide Red 120 also offers strong color strength and good dispersion.
Key Benefits
- Excellent hiding power and tinting strength
- Superior lightfastness and weather resistance
- Good dispersibility in solvent and water-based systems
- Low heavy metal content; conforms to common regulatory limits (confirm with SDS)
Applications
- Architectural & industrial coatings
- Plastics & masterbatches
- Printing inks
- Concrete & paving coloration
Dispersion & Processing Recommendations
- For optimal performance, pre-wet with appropriate dispersant before high-shear milling.
- Use defoamers in waterborne formulations to avoid surface defects.
- Check compatibility with resin systems in small trials—performance varies by formulation.
