VT-284 High Performance Duct Sealant

High Performance Duct Sealant is a solvent-based indoor/outdoor air duct sealant for sealing fabricated joints and other types of air ducts where the duct systems will be subject to frequent oil or chemical contamination. 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. It works in heated environments as it can withstand service temperature up to 70 °C.  It is able to accommodate minor vibration and movement, stays flexible and does not crack. Excellent coverage rates can be achieved with easy brush-on application, hence provides low installation cost. Can be easily applied by brush, trowel, hand, spray or extrusion.
