The traditional building material wood has besides a variety of advantages,also some disadvantages.One of them is the combustibility.Wood is regarded as a normal inflammable without any special proof.Depending on implementation and processing it can even be classified as "easy inflammable"(e.g.2mm thick veneer)or as "hardly inflammable"(e.g.surface protection with fire retardant coating).Although it behaves very good as a structural component in fire hazards(long lasting load-carrying capacity of highly designed,wooden members,no sudden collapses and hardly any dimensional shifts),the use of combustible materials and furniture raises the overall fire risk significantly.One possibility to control the fire risk of wooden constructions is the use of intumescent fire retardant coatings.In 2001 and 2002 the FraunhoferWKI started two research and development projects in cooperation with Technical University Braunschweig,iBMB,Fraunhofer ICT and several industrial partners.Intention was the development of a high performance fire retardant coating with enhanced properties.
