Intumescent topcoat offers protection against fire

Friday, 4 June 2010

When fire attacks the topcoat it causes a chemical reaction which makes the topcoat expand to form a non-flammable protective layer that insulates the surface over which it has been applied.

The new "Crystic Fireguard 75PA Excel" intumescent fire protection topcoat is a product upgrade of the long established "Crystic Fireguard 75PA". The new, improved version, reformulated by Scott Bader’s R&D team, offers better fire retardant properties and handling, yet is still cured with a standard MEKP catalyst (2 % addition by weight). When fire attacks the intumescent topcoat it causes a chemical reaction which makes the topcoat expand to form a non-flammable protective layer that insulates the surface over which it has been applied. While it will not protect indefinitely from an unchecked fire, the new product can withstand a direct flame at a temperature of 700 °C for over 60 minutes without the laminate behind catching fire. This is a significant period of time to contain a fire and prevent it from rapidly spreading.
