ABSTRACT:
Hot melt adhesives which are especially suitable for use with heat-recoverable plastics articles such as heat-shrinkable sleeves, wrap-around sleeves and end-caps are based on a combination of selected polyamides of relatively low molecular weight and relatively high amine equivalent, especially those based on dimer acids, and compatible waxes, especially low molecular weight paraffin and polyolefin waxes. The adhesive compositions advantageously comprise a tackifier, especially an aromatic tackifier, and preferred compositions include a minor amount of a rubber modifying agent to improve their low temperature flexibility and high temperature stability.
