A Study of The Effect of Weathering on The Expansion of Intumescent Fire Retardant Coating

Fire protection systems are widely used in many industry facilities against the effects of fire. However, in some case it is found that the performance of fire protection systems has deteriorated because of weathering. The objective of this project is to study the effect of weathering on the expansion performance of intumescent fire retardant coating. The first part of this project evaluates the performance of intumescent coating after exposed to weather by using weathering chamber. It shows that the weather reduces its expansion performance. The second part of the project attempts to observe the effect of zirconium usage as filler in the intumescent coating.
