Description
At PILATO, we market red iron oxide (Fe₂O₃) for the industrial market in Spain. Through a company-wide, integrated quality management system, we ensure immediate product availability and an operational approach focused on meeting our customers’ delivery schedules and technical requirements, while integrating seamlessly into their supply chains.

Thanks to its high tinting strength, red iron oxide is used in the manufacture of pigments and colours for the ceramic sector, as well as in industrial paints, coloured cements and construction materials. It is the reference pigment for colouring mortars, concrete and precast units because of its stability against light and against the alkalinity of cement. In ceramics it is also used in engobes and bodies, and in the formulation of anticorrosive primers.

We supply red iron oxide in 25 kg bags and big bags, supported by agile logistics to facilitate its integration into processes already validated by our customers.

  • Frequently Asked Questions

Frequently Asked Questions About the Red Iron Oxide

Why is red oxide more stable in firing than the yellow grade?

Because the red grade is already iron(III) oxide, Fe₂O₃, the form into which the yellow grade evolves on dehydrating. Having no water to lose, it does not change tone as it passes through that temperature range, which makes it more predictable in firing processes.

Yes, that is its most widespread application in construction. Iron oxides withstand the alkalinity of cement and exposure to light, the two usual causes of colour loss outdoors, which is why they are used in exposed concrete, mortar and precast units.

As well as providing colour, it acts as a film-filling pigment, helping to make the coating more compact and opaque to radiation. This is a classic use in primers and protective paints on metal substrates.
