Abstract
Flameproof and fireproof products are formed from a fire-unstable material coated with a polymeric material which is capable of intumescing beginning at a low temperature and has adhesive qualities in conjunction with the fire-unstable material. Upon the application of heat or flame to the products, the coating material copiously intumesces to form a protective thermal insulating foam barrier which prevents the fire-unstable material from igniting or degrading to the point of evolving flammable gases or losing its dimensional stability. Continued application of heat or flame will cause the foam to char but will not destroy the products for a suprisingly long time. The polymeric coating material comprises the resinous reaction product of phosphoric acid and a reducing sugar with a hardener and containing at least one modifying agent capable of rendering the coating material highly and permanently intumescent at a low initiating temperature even after prolonged storage of the flameproof and fireproof product. The modifying agent may be monoethanolamine, diethylamine, morpholine or mixtures thereof.
