Intumescent coating

What is an Intumescent coating?

An Intumescent coating finish looks similar to a paint finish, however, at high temperatures (for example in a fire), the increase in temperature causes a chemical reaction. The intumescent coating then expands to many times its original thickness (in an ideal environment this can be up to as much as 100 times), which then provides an insulating, protecting foam-like coating.
Intumescent coating is designed to insulate and protect both steel and timber structures. It helps to prevent the temperature from rising which could cause structural failure and fire with timber.

How does Intumescent Coating work?

Three key components are bound in a solvent or water-borne polymeric binder, the expansion process is caused when these components interact. These components are:
• Acid source: ammonium polyphosphate
• Expanding agent: melamine
• Carbon supplier: polyols as starch, pentaerythritol
Other components are added to improve the paint properties which improve application and drying speed.
