Abstract
Adhesives and coatings, especially two-component epoxy laminating adhesives, are prepared so as to be flame-resistant in the so-called part B or polyamide component thereof by including in that component a chlorinated hydrocarbon solvent together with an adduct of a polyamide and an aromatic hydroxy or epoxy compound. By this approach, the amine is tied up and is rendered resistant to premature reaction with the chlorinated hydrocarbon solvent within the part B component, which premature reaction would lead to the formation of undesirable crystals within the part B component and reduce its pot life. When the part B component is blended with an epoxy-containing part B component, the polyamine adduct gradually disassociates in order to free the polyamine to catalyze setting of the two-component system, particularly the epoxy resin of the part A component.
