Polywater’s foam duct sealants have a proven track record for providing durable and reliable protection in the toughest environments.
Polywater FST Duct Sealant is used to protect mission-critical electrical and telecommunication systems from water, gases, and other unwelcome intrusions.
The closed-cell, foaming caulk technology evenly flows around cables and in conduit space to create a strong bond.
The electrical conduit sealant expands and completely cures into a rigid, robust seal without relying on environmental moisture.
