AkzoNobel unlocks more sustainable coatings after biomass breakthrough

Published on : Thursday, December 31, 2020

A world of possibilities for paints and coatings has been unlocked by research being conducted by AkzoNobel, in collaboration with the Dutch Advanced Research Center Chemical Building Blocks Consortium (ARC CBBC).

The breakthrough innovation involves the development of a more sustainable way of making resins, which could pave the way for the introduction of futuristic functionality – such as intelligent paint that uses controlled release of active ingredients, or the ability to add new functionality during the lifetime of a coating.

The new process uses bio-based monomers to make the resins, rather than the traditional oil-based. Requiring just UV light, oxygen and renewable raw materials, patent applications have already been filed for resins and coatings made with monomers derived from sugar derivatives isolated from biomass.

“There’s no doubt we’re on the verge of progressing to the next level of coatings technology, thanks to this fantastic example of collaborative innovation in action,” explains Klaas Kruithof, AkzoNobel’s Chief Technology Officer. “We’re opening up a new future for paints and coatings by using sustainable building blocks that will enable us to explore and develop some really exciting functionalities for our customers.”

The process uses bio-based monomers to make the resins. Biomass is cracked by using acid to produce the sugar derivative (furfural). Using light and oxygen and adding different alcohols produces monomers that can be polymerized into coatings using UV light.

“Faced with the challenge of developing the sustainable chemistry of the future – a major goal of the ARC CBBC – I’m extremely pleased with these game-changing results,” adds Feringa. “They show that a material for coatings can be produced from biomass using a sustainable chemical process.”

“We’ve still got a long way to go in terms of exploring the scope of the technology, but it will almost certainly define the future of our products,” continues Kruithof. “By 2040 or 2050, there’s also a good chance we might only be using bio-based monomers in our resin production, which will help us to reduce the overall carbon footprint of our products.”

The biomass breakthrough is the latest example of the progress AkzoNobel is making in its search for sustainable solutions, having adopted a People. Planet. Paint. approach to sustainability. A detailed explanation of the science behind the development of the new process can be found in a research article which has just been published in the journal Science Advances.
