Introduction
Iron Oxide Black 722/330/380, also known as Pigment Black 11 (C.I.77499, CAS 1317‑61‑9), synthetic magnetite Fe₃O₄ inorganic pigment. It delivers deep pure black tone, high hiding power and excellent tinting strength. It features outstanding alkali‑resistance, UV‑weather fastness and chemical inertness. Stable color in cement concrete system, also performs well in coating and rubber processing. Widely used for construction building materials, concrete bricks, paving blocks, industrial coatings, plastic masterbatch and EPDM rubber granule for playground.
