  13. 13. POINT-OF-APPLICATION • TO PRODUCE THE PERFECT BEAD OR SPRAY PATTERN, IT IS ESSENTIAL TO DISPENSE THE SEALER OR ADHESIVE AT EXACTLY THE RIGHT VISCOSITY • THIS MEANS CONTROLLING THE TEMPERATURE OF THE MATERIAL AS IT IS BEING DISPENSED Saint Clair Systems © All rights reserved ISO 9001:2016 Certified 13
  14. 14. THE GOAL THE GOAL IS TO STABILIZE AND OPTIMIZE THE TEMPERATURE OF THE SEALER OR ADHESIVE AT THE POINT OF APPLICATION WHICH, FOR MOST SYSTEMS, IS THE NOZZLE ORIFICE… Saint Clair Systems © All rights reserved ISO 9001:2016 Certified 14
