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 FST™mixture 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.
