Abstract
Disclosed in an intumescent coating composition comprising an aqueous mixture of a water soluble alkali metal silicate, a hydrated metal silicate clay, and an inorganic particulate material which, when exposed to flame temperatures, endothermically releases a nonflammable gas. The coating can be applied to metal, wooden and foamed polymeric materials and serves to provide a thermal barrier against the effects of overheating.
