Industrial Filler Grade Limonite

 Thanks to its high iron oxide content and earthy yellow-brown to dark brown color tone, limonite powder performs both as a cost-effective filler and a natural pigment in industrial products. In the paint and coating industry, industrial filler grade limonite powder improves opacity, color stability, and film durability while helping to optimize formulation costs. Its good dispersibility makes it suitable for solvent-based and water-based coatings, primers, and industrial paints. In construction materials, limonite powder is widely used in cement, mortar, plasters, tiles, and concrete products, where it contributes to color uniformity, bulk density control, and mechanical strength.

The material is also applied in rubber and plastics compounds, where it functions as an inert mineral filler, enhancing dimensional stability and abrasion resistance. In addition, industrial limonite powder is used in foundry applications, refractory blends, bricks, and ceramic bodies, benefiting from its thermal stability and natural mineral origin.
