Hot-melt adhesives have been developed to bond polar and nonpolar mate
rials. This paper describes adhesives based on polyamide resins and on
polypropylene resins. Applications in the cable industry are presente
d to illustrate the potential utility of the newly developed hot melts
. Additional laboratory data suggest that the new series of products c
an bond a variety of difficult substrates and resist degradation in ac
idic or basic environments.
