Avoid mixing with other hot melt adhesives since different products could be incompatible. Incompatibility can lead to nozzle choking. For smooth and consistent flow output through the nozzle, the temperatures in the hot melt
applicator tank, hose and nozzle should be similar. Generally the temperature of the hose is maintained 2°C higher than the tank and the nozzle another 2°C higher than the hose.
