Abstract
Compositions useful in forming intumescent coatings are provided. These compositions are based on a reaction between phosphoric acid, melamine and monoammonium phosphate, which renders the monoammonium phosphate substantially less soluble while retaining its low dissolution temperature. Intumescent coatings utilizing the above-technology are disclosed as is a method of manufacturing these coatings.
