Duct liner is typically attached to duct walls by two fastening methods, one with mechanical fasteners and the other with adhesive. Mechanical fasteners are utilized to prevent delamination of the liner while adhesives bond the liner to the metal ensuring that airflow can not intrude between the two materials. The choice of an adhesive is affected by several factors some of which are, the method of application, acceptable dry time, solvent-type. Duro Dyne® PAW40 is an acrylic water-based, pressure sensitive adhesive specially formulated for duct liner applications. It has an aggressive tack and is ready to use. PAW40 sprays on white and dries clear.
