AS-1720

Water-based Duct Sealant

ALSEAL AS-1720 is a water-based indoor/outdoor air duct sealant for sealing fabricated joints and other types of air ducts. It performs as a tough and flexible adhesive and sealant on the joints and seams, thereby effectively blocks the infiltration of gases, dust and other contaminants and the exfiltration of conditioned air. Excellent coverage rate can be achieved with an easy brush-on application, which helps reduce installation cost. The thixotropic consistency of the sealant allows easy application by brush, trowel, hand, spray or extrusion. It is compliant with FDA 21 CFR 177.2600 (e) & (f).

Ideal for sealing fabricated joints and seams of sheet metal air ducts, fibreglass duct board, thermal insulation, crawl space vapour barriers, house wrap, and other types of air ducts.
