CORE-SHEATH FILAMENTS AND METHODS OF PRINTING AN ADHESIVE

A core-sheath filament having a non-tacky sheath and a hot-melt processable adhesive core, the sheath exhibiting a melt flow index of less than 15 grams per 10 minutes, is provided. Methods of making the core-sheath filament and methods of using the core-sheath filament to print a hot-melt processab...

Zusammenfassung:	A core-sheath filament having a non-tacky sheath and a hot-melt processable adhesive core, the sheath exhibiting a melt flow index of less than 15 grams per 10 minutes, is provided. Methods of making the core-sheath filament and methods of using the core-sheath filament to print a hot-melt processable adhesive onto a primer-treated substrate surface to provide a structural bond are described.
