Beschreibung
Zusammenfassung:	An intumescent coating composition comprising an epoxy resin binder, an epoxy reactive diluent, a curing agent and an acid catalyst, wherein the curing agent is comprised of a mixture of polyamide, polyetheramine and an amine functional monomer and wherein the acid catalyst is effective to form a phosphoric acid on thermal decomposition and wherein the coating composition has a viscosity of between 20,000 and 140,000 mPa/s at 20 ?C and shear rate 1.5 s-1 . The invention also extends to a coated substrate, coated on at least a portion thereof with said intumescent coating composition.
