The newly-developed powder coating Interpon D2525 from AkzoNobel can reflect much of the near-infrared radiation from any aluminium substrate to reduce thermal stress and prevent the unwanted heat accumulation.

The international paints and coatings supplier AkzoNobel has launched Interpon D2525 Low Solar Absorption, a powder coating that enables better and more sustainable architectural designs by counteracting the unwanted heat build-up produced by the sun's rays, while reducing the carbon footprint of buildings in hot cities.

Technically speaking, Interpon D2525 Low Solar Absorption contains a special pigment that helps to reflect much of the near-infrared (NIR) radiation, which accounts for more than 50% of the total radiated solar energy, from any aluminium substrate it coats. This has a dual effect:

  • It reduces thermal stress on the coated surface, thus increasing the life of the coated parts and contributing to the sustainability of the project.
  • It prevents the unwanted accumulation of heat diverted from the cladding surface inside the building, creating so-called urban heat islands, particularly evident in densely populated built environments.

“Challenging environments need robust innovation that can handle the heat over the long term and, crucially, deliver on sustainability. With our LSA range we’re proud to be giving architects a new way of creating better environments that allow people to enjoy the sun and its benefits and deliver spaces in which they can thrive for generations to come. When the heat is on, architects know they can trust Interpon to deliver!” has stated Bob Dirks, Global Segment Manager Architectural at AkzoNobel Powder Coatings.

Interpon D2525 is recommended for new construction or renovation of the building envelope, as it helps architects to design more comfortable spaces in which to live and work and to better enjoy the summer heat. Furthermore, air conditioning units do not have to work as hard to keep buildings cool and therefore consume less energy, adding to its sustainability credentials. Furthermore, it is free of volatile organic compounds and is available in a range of different colours and finishes that can be customised on request.

Lastly, Interpon D2525 Low Solar Absorption is supported by an Environmental Product Declaration (EPD) – an independent verification of a product's environmental impact across its whole lifespan, from initial production to end-of-life disposal or recycling. It benefits to some of the leading green building schemes, such as LEED (Materials and Resources) and BREEAM (Materials) certified building projects.
