Dutch company develops a self-cleaning paint – a sustainable innovation

Painting house exterior

Homeowners know that the exterior paint job on their home will only last so long – about ten years or so. Then it’s time to do it all again!

But Dutch chemical and coatings company AkzoNobel has been working on the problem and they’ve come up with an innovative solution. One of the company’s product developers, Dr. Peter Greenwood, figured out that by adding colloidal silica to its paints, it would last up to 16 year – 25 percent longer than the standard product.

AkzoNobel;s new paint products live up to its Planet Possible approach to sustainability. They feature the benefits of being self-cleaning, longer-lasting and more durable to a range of environmental conditions (such as extreme temperature and sunlight exposure). The paints were used at several test sites as part of a rigorous testing process.

“In this test station the panels get exposed to a lot of UV lights as well as different weather conditions. Sometimes it’s very cold, sometimes it’s quite hot. So it’s a really tough test. So if the panels can survive here, they can survive anywhere,” Jenny Lundegård, Innovation Manager at AkzoNobel, explains in the video. “We are all very proud of being a part of this. It’s really something extra to see your product out on the shelves and know that you made a sustainable difference.”

This product development is just one of several recent sustainability innovations from this Dutch company. It is developing an urban resilience guide for cities as part of the Rockefeller Foundation’s 100 Resilient Cities initiative, in partnership with The Nature Conservancy, Risk Management Solutions and Veolia. The goal of this project is to provide critical tools to help cities around the world become more resilient to the shocks and stresses that are a growing part of the 21st century. The announcement was made in late September at the Clinton Global Initiative Annual Meeting in New York City.

“If a paint can last longer, its longevity is one of the key parameters for the environmental impact of a paint,” said Greenwood.

This durable and long-lasting paint is an innovation that will surely be welcomed by homeowners everywhere.
