Surface coatings of melamine-modified urea-formaldehyde resins (MUFs) containing ammonium polyphosphate (APP have been shown to significantly improve the fire retardancy of wood by prolonging the ignition time and reducing the hea release rate, total heat released, and mass loss rate. Dual protection of wood against both decay and fire has been proposed fo remedial situations and interior construction. In this study, the fire retardant MUF resin type 3 (MUF3)/APP mixture syste showed strong activity against wood decay fungi via an activity inhibition test. Two species of wood were subjected t steeping with the fire retardants MUF3/APP. The treatments were evaluated for fire and decay resistance using con calorimetry and fungal decay resistance tests. The results showed that MUF3/APP surface treatment can provide dua protection to wood against degradation by decay fungi and fire. © 2016 Forest Products Society.
