Yellow Ochre Powder

Commercial yellow ochre is available in several grades and varieties, including Natural Yellow Ochre, Golden Yellow Ochre, Light Yellow Ochre, and Deep Yellow Ochre, distinguished by iron oxide content, brightness, and processing level. These grades allow manufacturers to select precise shades ranging from soft pastel yellow to rich golden hues. Yellow ochre powder is extensively used in architectural and industrial paints, cement and concrete coloring, plasters, mortars, bricks, tiles, ceramics, putties, asphalt, rubber, plastics, and decorative coatings. Its natural stability makes it especially suitable for exterior applications where color permanence and weather resistance are required.

Key properties of yellow ochre include excellent lightfastness, high alkali and UV resistance, thermal stability, low oil absorption, and good dispersibility. Commercial particle sizes are typically supplied as fine grades below 10 µm for paints and coatings, standard grades of 10–45 µm for construction materials and plastics, and coarser grades above 45 µm for textured plasters and decorative finishes.
