• Application Method - Nozzle
• Lower temperatures than recommended can cause higher viscosity which result in reduced bond strength and reduced wetting.
• Depending on the construction of the equipment, a continuous heating above processing temperature can cause decomposition of the adhesive.
• Tank melters should use protective gases with < 5 ppm humidity, only.
• Swift®lock 4791 is moisture sensitive, therefore container must be kept closed.
