-
Durability: OXIDO DE HIERRO pigments are chemically inert and do not react with the other components of the concrete mixture. This stability ensures that the coloration of the pavings remains uniform and does not degrade over time due to chemical reactions.
-
Weather Resistance: Pavings made with Iron Oxide pigments are highly resistant to weathering, including exposure to rain, snow, and temperature fluctuations. This weather resistance helps maintain the structural integrity and appearance of the pavings over their lifespan.

OXIDO DE HIERRO Application:
* Used in many types of paints, including antirust paint, water-soluble indoor/outdoor paints and oil-based paints.
* Used for dyeing construction materials, such as mosaic bricks, for concrete bricks, pavement, colorful tiles, roofing tiles and man-made marble.
* Colors for ceramic body.
* Used in paper industry, esp. rice paper.
* Used for surface coloration of plastic epoxy floor, color for pitch.
* Used as a more fade-resistant dye for plastics.
