Fire retardant coatings have been an important part of passive fire protection system for protecting structures in wildland urban interface (WUI) fires. However, limited studies have been conducted on their effectiveness and performance after long-term weathering exposure. This paper presents a study on the effects of weathering on the performance of intumescent fireretardant coatings on wooden structures in the WUI. The main concerns of weathering effects are: 1) the reduction of ignition resistance of the coating layer after weathering; and 2) the fire properties of coatings after weathering as the coatings might contribute as a combustible fuel and assist the fire growth after ignition. The study evaluated three intumescent coatings which exposed to natural weathering conditions in three time intervals. More than 190 combustibility tests consisted of a bench-scale performance evaluation using a cone calorimeter were performed, and three radiative heat flux levels were used for each coating type and weathering period. The key findings for each coating type under different test conditions are discussed, and the performance evaluation criteria for the combustibility tests is presented. [ABSTRACT FROM AUTHOR] |
