AFT Sealant system

Polywater® AFT is a chemical cure, closed-cell sealant providing 3m of water-blocking performance in electrical and telecommunication conduits against insects, rodents, moisture, dust, and gases. The two-part, closed-cell AFT Sealant is durable and easy to install. AFT has excellent adhesion to a variety of conduits. AFT seals conduits with quicker installation and higher performance compared to duct putty or single- part insulating hardware-store foams. The two-part aerosol foam seals any size void and cures without exposure to air. AFT expands and cures to a rigid, closed-cell structure in minutes.
AFT creates an airtight, watertight seal. AFT can be used to seal service entrances, conduit, inner-ducts, inverters and combiners for solar installations, and riser poles for the electrical grid. AFT is reusable, and the fire-retardant seal is self-extinguishing.
