Description

A Foam Duct-Sealing System for 2-inch/50-mm or Larger Conduits.

FST closed-cell duct sealant provides superior pressure-blocking power in the toughest environments.  It stops methane and other gases to keep electrical systems intact.  FST Duct Sealant is stronger, more chemically resistant, and cures 50 times faster than open-cell aerosol foams. The FST seal has excellent adhesion to PVC, rigid steel, EMT, IMC, fiberglass and polyethylene conduits.  FST is a proven solution that has been used for years to protect switchgear, panels, riser poles, combiner boxes, meters, and all types of electrical and telecommunication apparatus.  It creates a semi-permanent seal and is reenterable.

A properly constructed FST seal is pictured on the left, installed in a transparent tube to show the structure of the seal inside the duct.  Damming strips are wrapped around the cables to create a void into which the two-part liquid FST mixture is injected.  The damming strips help contain the FSTmixture at the mouth of the duct while it expands and hardens into a strong, resilient seal.  The damming strips also separate cables so that the expanding foam can flow around them to prevent leakage between them.  Inject the sealant with a high-ratio caulking gun for immediate protection of high-value network assets.

Product/Package Notes:

Polywater® FST is recommended for 2-inch (51 mm) or larger conduits.  It comes in a multi-use single-plunger caulking tube that uses a standard high-ratio caulking tool (TOOL-250).

For smaller conduits the Polywater® FST MINI is recommended (see sidebar).

The kit packages come with all the components needed to complete a proper seal.
