Effects of Ultraviolet and Rain on the performance of Fire Retardant Coating

The fire protection of structural materials has become an important issue in the construction industry. The use of intumescent coating is one of the most effective ways to protect different types of substrate against fire including metals polymers, textiles and wood. This project is focusing on the performance of intumescent coating before and after being exposed to Ultraviolet and Rain. Intumescent coating is an insulating material designed to decrease heat transfer to a substrate structure. In the intumescent fire retardant (IFR) coating char thickness and its strength play a vital role to protect the base steel structure from the fire.
