Flame Retardant Radiation Curable Coating For Wood Application

Due to the continuous trend in more stringent safety regulations, search for polymers with flame retardant (FR) properties is important. In the case of coatings (radiation curable or conventional), their flammability can contribute to the fire propagation. In some wood coating applications, significant level of fireretardancy is required. In this paper UV-curable oligomers containing phosphorus FR moieties covalently bound to the backbone will be presented. It will be shown that their application in wood coatings significantly improves the fire-retardant properties of the coated materials.
