Iron Oxide Pigment Storage — Red Yellow Black Synthetic Inorganic Color Pigment Hopper

Storing Iron Oxide Pigment? Start Here

Iron oxide pigments, available in red, yellow, and black, are widely used for their color stability and cost-effectiveness. They're ideal for concrete pigmentation, industrial coatings, and plastic compounding. These pigments are non-combustible and stable across a wide pH range, making them versatile for various applications. Whether you're dealing with dry powder or aqueous slurry forms, understanding the right storage solutions is key to maintaining their quality and performance.

Can you store it in a poly tank?

Yes, you can store iron oxide pigments in poly tanks. Both dry powder and aqueous slurry forms are compatible with HDPE and XLPE tanks, making them a standard choice for storage. Polypropylene is also suitable for fittings and valves.

Abrasion: The Key Issue

One important consideration when storing iron oxide pigments is their abrasive nature. This can cause wear in pneumatic conveying systems, especially at high-wear points like elbows and pump components. Using hardened-iron or rubber-lined parts can help mitigate this issue.

The safety that actually matters

• Non-combustible: Iron oxide pigments are inherently fire-safe.
• Dust control: Manage dust at handling stations to prevent inhalation hazards.
• Material compatibility: Ensure all storage and handling equipment is compatible with iron oxide's abrasive nature.

Common questions

Can iron oxide pigments be used in concrete?

Yes, they are commonly used to color concrete and are stable over long periods.

What gasket materials should I use?

EPDM gaskets are standard, but Buna-N and Viton are also acceptable.

Is there a risk of contamination with aluminum tanks?

Yes, aqueous solutions can cause aluminum oxide contamination, affecting color.
