Abstract
A liquid intumescent coating composition comprising a resin system. The resin system comprises at least one polymeric component, one or more ethylenically unsaturated monomeric components and at least one intumescent ingredient. The coating composition is curable to a solid state in a free-radical polymerization reaction.
Claims24
A liquid intumescent coating composition comprising at least one polymeric component, said at least one polymeric component comprises solid thermoplastic resin, at least one ethylenically unsaturated monomeric component, and at least one intumescent ingredient component comprising an acid source in combination with another intumescent ingredient, and a chemical initiator for initiating a reaction to cure the coating composition to a solid state by free radical polymerization.
A method of curing a liquid intumescent coating composition to a solid state by free radical polymerization comprising the step of adding an organic peroxide initiator to the liquid intumescent coating composition, wherein the coating composition comprises at least one polymeric component, said at least one polymeric component comprises solid thermoplastic resin, at least one ethylenically unsaturated monomeric component and at least one intumescent ingredient component comprising an acid source in combination with another intumescent ingredient.
A liquid intumescent coating composition comprising a solid thermoplastic resin, at least one ethylenically unsaturated monomeric component, at least one intumescent ingredient comprising an acid source in combination with another intumescent ingredient, a peroxide initiator for initiating a reaction to cure the coating composition to a solid state by free radical polymerization, and a tertiary amine catalyst.
A liquid intumescent coating composition comprising at least one polymeric component, said at least one polymeric component comprises solid thermoplastic resin, at least one ethylenically unsaturated monomeric component, and at least one intumescent ingredient component comprising an acid source in combination with another intumescent ingredient, said coating composition curable to a solid state by free radical polymerization.
