DUCT SEALANT AND METHOD OF SEALING A DUCT

Abstract:

The present disclosure relates to a duct sealant, a kit for preparing the duct sealant, and a method of sealing a duct. The duct sealant comprises a curable plastic and a plurality of plastic pellets disposed throughout the curable plastic. The duct sealant is able to provide desirable properties such as quick curing, ease of installation, requires only a small thickness, and sufficiently seals the duct from gases and liquids. The duct sealant has a cellular sealant structure when cured, as the plastic pellets introduce weaknesses into the sealant that allows for easy and quick breakage/removal of the duct sealant with no damage to cables such as fiber optic cables being run through the duct.
