ARTICLE COATED WITH INTUMESCENT UNDERCOAT OF A SYNTHETIC RESIN, INORGANIC FOAM FORMING AGENT AND CARBON FORMING AGENT AND WATER-INSOLUBLE ORGANIC SOLVENT BASED RESIN OVERCOAT

摘要

An article having a fire resistant coating which includes an intumescent undercoat of an aqueous mixture of a synthetic resin, an inorganic foam forming agent and a carbon forming agent. Over the intumescent undercoat there is applied a nonflammable water-insoluble organic solvent based resin. This latter overcoat is essentially incompatible with the intumescent undercoat composition.
