ABSTRACT:
A thermoplastic tube for transfer of hydrocarbon fuel comprising an inner fluoroplastic layer and an outer polyamide layer bonded to the fluoroplastic layer wherein an adhesion promoter is included in at least one of the layers is disclosed. The adhesion promoter is an unsubstituted or substituted phenol salt of 1,8-diazabicyclo-[5,4,0]undec-7-ene on a novolac carrier which functions to increase the adhesive bond strength between the two layers. The adhesion promoter provides a chemically bonded adhesion in addition to the mechanical adhesion associated with extrusion or lamination of the layers.
