1. Product Description
Our Iron Oxide Pigment series provides premium, high-strength synthetic iron oxides. Available in a comprehensive color spectrum including Red (alpha-Fe2O3), Yellow, Black, Green, Blue, and Custom Blends. Offered as a dry, loose, spherical powder, they provide superior tinting strength, chemical resistance, UV stability, and weather fastness across all colors.
Key Applications
Construction Coloring
Used extensively to tint concrete blockwork, colored roof tiles, paving blocks, and decorative rendering with diverse color options.
Premium Plasters & Putties
Blends with Tamax White Cement and Hydrated Lime to create custom-colored, dampness-resistant finish plasters.
Coatings & Paints
Serves as primary colorants in architectural paints, primers, industrial floor finishes, and wood stains across various hues.
Safety Warning
The product is not classified as hazardous under EC directives or regional West African environmental regulations. Ensure standard dust protection (mask and safety glasses) is worn when handling loose powder in bulk.
Packing & Storage
Packaging Options:
- Supplied in heavy-duty 50lb (22.6kg) multi-walled paper bags.
Storage Guidelines:
Store in dry, secure facilities away from direct exposure to rainwater and extreme temperature fluctuations. Ensure bags are tightly sealed immediately after opening to prevent moisture absorption and external contamination.
