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 air flow 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 DTWACC+ is a CARB compliant, high performance aerosol, offering rapid setting and quick dry time. This adhesive is ideal for use on duct liner, duct wrap or on sheet metal.
