Polywater® AFT™ Aerosol Foam Sealant – Electrical Conduit Sealant

Polywater® AFT™ Aerosol Foam Sealant is a two-part, closed-cell urethane foam designed to block water, gas, and contaminants in electrical and telecommunication conduits. It provides a durable, airtight, and watertight seal that protects cables and equipment from moisture, dust, insects, rodents, and gases. This foam sealant is compatible with common cable insulation and conduit materials, making it suitable for use by electrical distributors, wire and cable suppliers, and switchgear suppliers requiring reliable conduit sealing solutions.
