At what temperature does intumescent paint react?

120°CIntumescent paint reacts when its temperature attains or exceeds 120°C, and the process results in a soft charring effect at its surface (which insulates and reduces transmission of heat into the substrate) and the release of water vapour (which helps to cool the substrate).

What is intumescent paint?

An intumescent coating is basically a paint-like material which is inert at low temperatures – under 200 ◦C – but reacts with heat. As the temperature rises, during a fire event, the intumescent coating swells and forms a char layer that covers the steel.
