Experimental Study of Fire Retardant Coating

Fire Retardant Coating (FRC) components have been studied and optimized in this work. Main components of FRC include; Polyammoniumphosphate, Pentaeritrol and Melamine. The results of thermal analysis indicate that decomposition of main components occur in the 220 to 790 oC temperature range. Thermal reactions of Penta-eritrol starts at lower temperatures followed by melamine undergoing structural changes around 250 oC. Polyammoniumphosphate show no weight reduction below 290?C. In addition to the main components there is a specific plasticizer in fire retardant formulation to improve properties of the coal layer. Beyond 500 oC only carbon in the form of coal remains.
