Together with BRUAG Fire Protection AG, Empa specialists have developed a new flame retardant for wood and wood-based materials. The colourless additive, which can be easily mixed with coatings and cellulose materials, opens up new applications for wood processing companies. Fire protection requirements are increasing worldwide - especially in public buildings and vehicle construction. This development means that more and more otherwise suitable materials such as wood can no longer be used in many buildings or means of transport and must be substituted by other products. The aim of the CTI funded research project was therefore to develop a flame retardant that increases the fire resistance of such materials without impairing the positive properties of the materials. The new flame retardant called AFA (Anti-Flame-Additive) meets these requirements: It is colorless and can be mixed with water-based paints or UV protective coatings and can be used not only as a coating but also as an additive in wood-based panels. In addition, it is free of bromine and boron and contains no halogenated organic compounds.
