A coating from nature (IMAGE) University of Groningen Caption Lignocellulose biomass is cracked using acid to produce furfural. Using visible light and oxygen, furfural is converted into hydroxybutenolide, which is then modified using different alcohols to produce alkoxybutenolide monomers, that can be polymerized into coatings using UV light.
