Nordson PURBlue 4
PURBlue 4 adhesive melters efficiently process moisture-cure reactives (PUR) from two-, three- or four-kg foil-encased slugs without the need for inert gas. The user-friendly design allows foil bags to be quickly, easily changed while graphical intuitive controls simplify programming and operation. PURBlue melters are designed specifically for simple, reliable operation; quick disassembly; and easy cleaning and maintenance. These true “melt-on-demand” systems process only the adhesive needed, reducing thermal stress and protecting bonding characteristics.
