Aqueous intumescent coating compositions which include a non-ionic surfactant having a hydrophilic-lipophilic balance (HLB) of 9 to 20, and substrates coated with the coating composition are disclosed. Inclusion of the non-ionic surfactant in the coating 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 to the same coatings lacking the non-ionic surfactants.

Surfactants for intumescent foam stabilization

Self-crosslinkable binder compositions which include a copolymer obtained by reacting a mixture of monomers in the presence of an organic solvent, wherein the monomer mixture includes a carboxylic acid monomer, a polymerizable ethylenically unsaturated monomer, and a crosslinkable acrylamide monomer. Intumescent coatings containing the self-crosslinkable binder, and substrates coated with the intumescent coatings are also disclosed.
