HVAC duct and electrical sealant
This acrylic latex sealant comes in a gray 10.5 oz cartridge and is formulated for HVAC, duct and electrical applications. It meets EPA Method 24, LEED Credit EQ 4.1, NFPA 90A, NFPA 90B, UL 181B-M and UL 723 standards. The product offers low VOC content and a mild odor for indoor use.
Installers needing mildew and UV resistance
The sealant resists mildew, mold and ultraviolet exposure while remaining nonshrinking across a service range of -25 to 220 degrees F. Full cure requires three days, so projects demanding immediate structural strength should consider alternatives. Buyers in restricted states cannot purchase this item.
