HVAC duct and electrical sealant
Ductmate GRFIBERSEALT is an acrylic latex sealant formulated for HVAC ductwork and electrical applications. The gray cartridge delivers a low-VOC, mild-odour compound that resists mildew, mould and ultraviolet exposure. It meets EPA Method 24, LEED Credit EQ 4.1, NFPA 90A, NFPA 90B, UL 181B-M and UL 723 standards.
Cartridge size and cure time
The product ships as an 11 oz cartridge, noted as 10.5 oz in the supplier title, and requires a standard caulking gun for application. Full cure is reached in 3 day, after which the seal remains nonshrinking across a service range of -25 Degrees F to 220 Degrees F.
No bundled accessories or software
The package contains only the sealant cartridge; no applicator gun, tooling nozzle or cleaning solvent is included. Installers must supply their own caulking gun and any surface-preparation materials required by the job. Buyers who need a complete kit with tools should look elsewhere.
