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.

Cartridge format suits standard caulking guns

The 11 oz cartridge fits common applicators for consistent bead application on ductwork and electrical penetrations. No additional tools or software are bundled with this sealant. LEED compliance supports green-building documentation requirements.

Questions about this item

What size caulking gun do I need for the 10.5 oz cartridge?

Use a standard 10.5 oz / 11 oz cartridge gun; the product ships in a cartridge of that size.

Can I apply this sealant over existing duct mastic that is already cured?

Yes, the acrylic latex formula bonds to clean, cured mastic and stays flexible from -25 °F to 220 °F.

How do I know the sealant has fully cured after three days?

The bead turns uniformly gray, feels firm and non-tacky, and meets the listed UL 181B-M and NFPA 90A/90B ratings.
