Abstract
Disclosed is a non-emissive, flame-retardant coating composition comprising a flame-retardant polymer; a solvent selected from water and/or a liquid, curable, non-flame promoting polyhalogenated solvent containing air-dryable functionality; and, optionally, a non-emissive, non-flame promoting surface-active agent selected from: a cationic, non-emissive, non-flame promoting, curable polyhalogenated compound containing an air-dryable group and a cationic surface-active group; an anionic, non-emissive, non-flame promoting, curable polyhalogenated compound containing an air-dryable group and an anionic surface-active group; and a nonionic, non-emissive, non-flame promoting polyhalogenated compound containing a nonionic surface-active group. Also disclosed is a method for reducing the emissivity of a polyamine/polyamide hardener for an epoxy resin wherein volatile, mobile, low molecular weight amine components in the hardener are reacted preferentially with a trapping agent selected from an epoxy compound and an alpha-, beta-ethylenically unsaturated carbonyl compound. Further disclosed is a method for reducing the tendency to crystallize and to retard dispersion in water of a highly ha…
