Abstract
An intumescent coating composition that includes an epoxy resin binder, an epoxy reactive diluent, a curing agent and an acid catalyst. The curing agent includes a mixture of polyimide, polyetheramine, and an amine functional monomer, wherein the amine multifunctional monomer is different from the polyetheramine. The acid catalyst is effective to form a phosphoric acid on thermal decomposition. The coating composition has a viscosity of between 20,000 and 140,000 mPa/s at 20° C. and shear rate 1.5 swhen measured within 1 minute of mixing the components. The invention also includes a coated substrate having the intumescent coating composition coated on at least a portion thereof.
