Abstract: The expandable, flame-resistant (flame-retardant) coating compositions consist at least of from 4 to 25 % by weight of a film-forming binder, from 10 to 40 % by weight of ammonium polyphosphate, from 8 to 40 % by weight of at least one substance which is carbonised under the effect of heat, from 6 to 25 % by weight of an expansion (blowing) agent, from 0 to 5 % by weight of dispersants, and from 0 to 25 % by weight of fillers. In these coating compositions, ammonium salts of alkyl phosphates are present as substances which are carbonised under the effect of heat and/or as expansion agents, and as additional acid donors.

Abstract: The novel feature in an expandable, halogen-free, flame-retardant coating composition containing an epoxy resin, polyphosphoric acid ester (I) and a hardener is that it comprises 75-95 parts wt. epoxy resin and 5-25 parts wt. (I), with the wt. ratio (resin + (I)) : hardener being 1.1-10 : 1. Claimed production is by first reacting the resin with (I) and then treating the reaction product in a second step with the hardener.
