THE UNIQUE BENEFITS OF REACTIVE HOT MELTS, KNOWN AS MOISTURE-CURING POLYURETHANES, HAVE ALLOWED THE ENTRY OF HOT MELT TECHNOLOGY INTO APPLICATIONS PREVIOUSLY RESTRICTED TO OTHER ADHESIVE FORMULATIONS. THESE HOT MELT MATERIALS ARE CHARACTERIZED BY SPEED OF SET AND MANUFACTURING EFFICIENCY, COUPLED WITH SUPERIOR BOND STRENGTH AND TEMPERATURE, AND CHEMICAL RESISTANCE. ONE APPLICATION WHERE MOISTURE-CURING POLYURETHANES HAVE PROVEN EFFECTIVE IS IN THE MANUFACTURE OF INSULATED GARAGE DOORS. THIS PAPER REVIEWS THE DISTINCTIVE APPLICATION BENEFITS AND LIMITATIONS, APPLICATOR DESIGN, AND MATERIAL OPERATION CONSIDERATIONS.
