Development of fire retardant composite panels. Part V. Improvement of fire performance of ceiling tile via surface coating with commercial fire retardant coatings
To improve the flame resistance of low-density fiberboard (ceiling tile), a laboratorial study was carried out to coat the commercial ceiling tile with three commercial fire retardant coatings (WT-102, Safe-T-Guard®, RUFR-1000). In general, the surface coating of low-density ceiling tile with the three fire retardant coatings effectively improved the fire performance of the board. The ceiling tile coated with RUFR-1000 performed better than those with WT-102 and Safe-T-Guard® in terms of reduced panel consumption, net flame advance, insulation value, and char index according to ASTM D 3806.
