摘要： Intumescent compositions are described which when deposited on a substrate protect the substrate against heat and fire damage for an appreciable time, and these compositions are readily removed from the substrate by water washing or water scrubbing both before and after intumescing. Another advantage of these compositions is that they give off very little smoke when exposed to heat and fire. The most effective of these compositions comprise monoammonium phosphate and/or diammonium phosphate as a heat- and fireproofing agent, urea and/or cyanoguanidine (dicyandiamide) as a gas forming or gas generating agent to promote the intumescence, sucrose (sugar) together with the phosphate to promote initial intumescence at low temperature and titanium dioxide as a heat-reflecting agent. Certain possible alternatives to the compounds named above are also named.
