Abstract
A plastic coating is provided which protects coated structures from flame. The coating is a product resulting from mixing an aromatic polyisocyanate, an aromatic polycarboxylic compound, and furfuryl alcohol at a temperature less than 80.degree. C. The structure to be protected from flame is coated with the product and the product is then dried. If the coated structure is exposed to flame, the coating intumesces to form a flame-resistant foam which protects the structure.
