Intumescent coatings are passive fire protection measures which swell up when heated (in a fire for example) an-d protect the material (steel, plasterboard or wood ) underneath it, from fire. As the intumescent layer swells up, it increases its surface volume, which then helps to decrease the intensity of the flames. The top coating produces a light char as it is burnt, which makes it a poor conductor of heat and fire spread.
Due to COVID-19 pandemic, the global Intumescent Coatings market size is estimated to be worth US$ 775.
