Abstract(s)

Intumescent coating is a reactive chemical material, which is used as the main fire protection material to steel structures. When intumescent coating is exposed to fire, the chemical components in the intumescent coating react to cause the coating to swell forming a lightweight flame-retardant char to protect the steel substrate from excessive rise in temperature. However, exposure to long-term environmental conditions can cause the intumescent coating to lose some of the reactive materials, thus reducing the effectiveness of the intumescent coating over time. Because fire safety requirement is throughout the entire life of a building structure, which may last many tens of years, it is important to understand the long-term protection performance of intumescent coating under exposure to environmental conditions, [1].
