ABSTRACT:
There is disclosed, in one aspect, an emulsion of a hydrophilic epoxy resin containing foam forming additives which impart fire retardant properties and which compositions are useful for coating substrates. These compositions comprise (a) foam-forming, gas-evolving and/or chain-terminating additives which have an endothermic reaction at elevated temperatures and/or fillers and, (b) epoxide resin as the binder. This resin has been cured with an amine curing agent. In another aspect, the present invention comprises a method for producing fire-proof layers of structures which must be protected from fire. This method comprises coating at least part of that structure with the composition described above.
