Abstract
A water-based liquid intumescent coating composition comprising a modified binder resin component is described herein. The binder resin component comprises at least one polymeric component, one or more ethylenically unsaturated co-monomer components and at least one intumescent ingredient. The coating composition is curable to a solid state in a free-radical polymerization reaction. The described composition demonstrates improved char formation and passive fire resistance.
