PURBlue 4 melters efficiently process moisture-cure reactive adhesives, such as polyurethanes (PUR), from two-, three- or four-kilogram foil-encased slugs. A user-friendly design combines simple, reliable operation with easy cleaning and maintenance. PURBlue melters provide the ability to easily use small volumes of PUR for increased productivity and reduced adhesive waste.

• Reduce thermal stress and protect bonding characteristics with true melt-on-demand processing.
• Minimize adhesive residue with adjustable force piston providing optimal contact between adhesive and melting grid.
• Simplify maintenance with single-tool, quick-release fasteners on all panels and covers.
• Ease start-up and operation with user-friendly controls, graphic indicators, week/day timers and I/O interfaces.
• Eliminate need for inert gas to use PUR adhesives
