Introduction to Iron Oxide Pigments
Iron oxide pigments are high-performance, inorganic colorants widely valued for their durability and versatility across numerous industrial sectors.
Exceptional Durability: They offer outstanding resistance to UV light, weathering, and extreme temperatures, ensuring long-lasting color.
Excellent Hiding Power & Color Stability: They provide strong, consistent coverage and do not fade over time.
Chemical Inertness: Resistant to alkalis, weak acids, and solvents, making them stable in various formulations.
Non-reactive and Environmentally Safe: They are non-toxic and possess excellent stability.
Primary Industrial Applications:
Coatings & Paints: Used in industrial and protective coatings for metals, and architectural paints for their weathering resistance and color consistency.
Construction: The largest application, where they are used to permanently color concrete (e.g., paving stones, roof tiles), masonry blocks, mortar, plaster, and stucco.
Plastics & Polymers: Employed for coloring various plastic products, providing heat stability during processing.
Compliance with Construction Standards:
Iron oxide pigments are formulated to meet critical international construction material standards, including:
ASTM C979: Standard Specification for Pigments for Integrally Colored Concrete.
EN 12878: Pigments for the colouring of building materials based on cement and/or lime – Specifications and test methods.
