Polywater | FST™ Foam Duct Sealant

FST™ Foam Duct Sealant

FST™ Duct Seal is a "closed cell foam", which is superior to "open cell" spray canned foams. The kit contains a cartridge filled with a two-part foam base, which is mixed in equal parts as it is pushed through a mixing nozzle. When mixed and injected, the foam expands and hardens, keeping water, acids, greases, gases, insects and rodents, etc. out of the conduit. The foam has good wetting and adhesion to metals, plastics and concrete. A separate, reusable ratchet application tool is used to inject the foam.

FST™Duct Sealant is available in two cartridge sizes. FST-250 is used for 2-inch (50mm) or larger conduits and comes in a multi-use single-plunger caulking tube that uses a standard high-ratio caulking tool (TOOL-250). FST-MINI is used for 1.5-inch (38mm) and smaller conduits. It comes in a dual 50 ml cartridge with 1:1 ratio. TOOL-50-11 is needed to apply FST-MINI. FST™ foam wets and adheres to metals, plastics and concrete and can seal ducts of different sizes, base materials and shapes. It conforms around complex cable fill configurations. A kit contains everything required to install the duct block (application tools available separately).

Cured foam is strong, resilient and chemically resistant Provides superior protection in adverse field conditions and where cable movement is present.
Can hold 22 feet water-head pressure over an extended period of time.
Will tolerate cable movement.
Foam expands and cures quickly even when water is present Seal ducts quickly and neatly.
Two-part foam is mixed in nozzle as it is injected -- no mixing required Saves time with no measuring.
Packages are resealable, no waste.

Polywater® FST™ Duct Seal

A properly constructed FST™ Duct Seal example is shown at right in the clear conduit demo. Note the placement of the "damming" strips wrapped around the cables. The dams create the void into which the liquid FST™ foam is injected and hold the rapidly expanding foam in place while it cures. For additional information read the Application Instructions for FST-250

The FST™ Duct Seal example shown at right is a cross-cut duct to show FST™ closed cell foam technology at work surrounding the cable to maintain a good seal.
