(HLB) of 9 to 20, and substrates coated with the coating composition are disclosed. Inclusion of the non-ionic surfactant in the coating GC 1-1 compositions is found to reduce char cracking and improve the mechanical strength, cell size, and cell density for intumescent chars © formed when coatings deposited from the coating compositions are exposed to open flame and/or elevated temperatures, as compared N to the same coatings lacking the non-ionic surfactants. 0
