PUR hotmelt adhesives adapt to many processes and applications due to their very favorable properties.
The evolution of manufacturing processes includes the adaptation to change. Many of today's modern production facilities are using the latest in CNC equipment as well as other enhanced production machinery to maximize their output. This increased productivity has created serious bottlenecks in the area of gluing.
Many basic assembly operations use adhesives with set times and bond characteristics using technology developed during the World War II era which has since remained relatively unchanged. These adhesives, most specifically PVAs, while suitable in some ...
