Seal Moisture, Gases, and Rodents Out of Conduits and Risers
Polywater AFT-16 closed-cell sealant provides 10 feet of water-blocking in electrical and communication ducts. Because it is a two-part system, humidity is not required for the cure. There is a consistent cure strength throughout the seal. Closed-cell AFT Sealant offers durability as well as ease of use.
AFT shows excellent adhesion to a variety of conduits. AFT seals conduit faster and with better performance than duct putty or one-part insulating foams. The two-part aerosol foam expands to fill any size void. The AFT aerosol spray package comes with multiple actuators, which allow the sealing of multiple ducts.
Seal service entrances, conduit stub-ups, and innerducts with AFT foam. Also protect inverters and combiners in solar panel installations. Another use is sealing the top of riser poles. Use AFT foam wherever you want to storm harden and thus protect the grid.
Polywater AFT-16 passes UL94 with a Class HBF fire retardant rating. It is UL recognized and the seal is self-extinguishing.
Specifications and Applications:
Cable Compatibility: AFT two-part foam sealant is compatible with common cable jacket materials. The cured foam is an inert solid that does not affect cable components.
Cure Rate: AFT two-part foam sealant can be used at temperatures down to 45° F (7° C). At lower temperatures the reaction slows, but the sealant will completely foam and cure with time. AFT foam expands two times its volume as it is dispensed. Full expansion is complete in under 2 minutes at 70° F (21° C). It will take 3 to 5 minutes to be tack free. During this time do not move cables or touch foam.
Approvals/Codes: AFT is UL recognized and passed UL94 with a Class HBF fire retardant rating. Polywater AFT Sealant meets NESC code sections 322 B4 and 355 D; and 2008, 2011, 2014, and 2017 NEC conduit sealing code requirement Articles 225.27, 230.8, 300.5 (G), 300.7 (A) on Raceway Seals, and 501.15 (B)(2).
Application: Shake can for 60 seconds to mix. Lift hinge and insert dispensing nozzle into top orifices so that the arrow lines up with the dispensing nozzle. Invert aerosol can. Insert nozzle all the way into the seal space and fully squeeze the hinge to spray sealant into the conduit.
