HVAC Duct Sealant
This one-gallon acrylic latex sealant is formulated for HVAC ductwork and electrical applications on metal surfaces. The gray compound meets UL 181B-M and NFPA 90A/90B standards for use in air-distribution systems. It is LEED compliant and satisfies EPA Method 24 low-VOC requirements. Builders specifying materials for commercial or residential duct sealing will find it listed for those purposes.
Pail Format and Cure Schedule
The 128 oz pail supplies enough volume for long seams and multiple joints without frequent container changes. Full cure is reached in three days, during which the material remains non-shrinking across a service range of -25 °F to 220 °F. The pail packaging suits brush or trowel application directly from the container. Installers who need cartridge dispensing or faster skin-over times will need a different product format.
Mildew and Mold Resistance
The cured sealant resists mildew and mold growth inside duct cavities where condensation can occur. Low VOC content and mild odor reduce occupant exposure during and after application. Compliance with UL 723 surface-burning characteristics supports fire-safety documentation. No primer, reinforcement tape or specialised application tools are included with the pail.
