Back
At the end of a shot, a small amount of material is drawn
back into the static mixer to prevent extra material from
being dispensed. If too much snuff back occurs air will
enter the static mixer and can travel up into the dispense
valve. If too little snuff back occurs the materials may
drip out of the static mixer and affect dispense quantity.
