Bostik Contact Adhesive 2700/2701 -Red/Clear

JOWAT HOTMELT 280.50 GLUE NATURAL

PUR hot melt adhesives can be processed on throughfeed lines at different feed speeds, as well as on roller and nozzle applicators. All parts of the melting and application units coming into contact with the adhesive should have a non-stick coating to prevent possible catalytic reactions due to metal contact. A non-stick coating will also facilitate a considerably easier cleaning. The melting and application units should be equipped with a precise temperature control to prevent local overheating and unwanted secondary reactions. Heating the adhesive to a temperature above the recommended processing temperature will usually lead to a fast increase in viscosity of the melt due to a so-called thermal crosslinking reaction in the adhesive (the allophanate reaction), which is triggered by heat and does not need moisture.
