Effects of Rockwool and Glasswool on Thermal Performance of Intumescent Coating

This research is aimed to incorporate rockwool and glasswool fibres into an intumescent coating. Briefly, intumescent coating is a fire retardant coating that protects structural materials against fire. This research studies the effect of rockwool and glasswool on thermal performance of intumescent coating. The composition of the fibres is varied to get the best sample. The results show that the addition of rockwool and glasswool will increase the thermal performance, which is the intumescent coating resistance to fire. The samples have gone through Scanning Electron Microscope (SEM) for analysis. From there, the characteristics of the samples’ char are achieved. The thermal performance is determined by direct fire test. The data of time versus temperature is attained and that could conclude the effect of rockwool and rockwool on thermal performance of intumescent coating.
