A fire-retardant coating for wood made from food-industry waste

Abstract

Wood is regaining popularity due to increased environmental awareness but requires protection against humidity, UV radiation, stains, and fire. We have developed a sustainable and protective coating derived from biogenic residues. This non-flammable coating enhances thermal stability, delays combustion, and prevents flame spread. Additionally, it protects against moisture by forming a water-insoluble film after polymerization. The coating can be applied from an aqueous solution, adheres well to wood surfaces, and is made from renewable sources, ensuring ecological sustainability.
