ABSTRACT:
A mixture of benzyl alcohol and a hydroxy benzene is disclosed, for use in the bonding together of polyamide articles. In one embodiment, the mixture comprises 5 to 50% by weight of benzyl alcohol, 20 to 90% by weight of phenol; and 5 to 30% by weight of polyamide. In another embodiment, the mixture comprises 20 to 60% by weight of a benzyl alcohol, 20 to 60% by weight of ortho-dihydroxy benzene and 20 to 60% by weight of a lower alcohol having one to four carbon atoms. The mixture may be applied to a polyamide article, which may then be contacted with a second polyamide article and heated to effect bonding. In another embodiment, a pattern of the mixture may be applied, for instance on a polyamide film, the pattern corresponding to the bonds required in the polyamide article being manufactured. For example, the composition may be used to bond film or sheet together so as to form fluid flow passages therebetween e.g. as in a heat exchanger.
