Polywater AFT Spray Foam Sealant | Airtight & Watertight Duct Sealing

Polywater AFT Spray Foam Sealant | Airtight & Watertight Duct Sealing

Polywater AFT Spray Foam Sealant is a two-part expanding polyurethane foam that creates airtight, watertight, and insect-resistant seals around conduits, ducts, and cable penetrations. Designed for quick and clean application, it prevents air leakage, water intrusion, and gas migration in electrical, telecom, and fiber systems.

Ideal for both new and retrofit installations, Polywater AFT expands rapidly to fill irregular openings and gaps in walls, conduits, or enclosures—forming a durable, flexible seal that maintains adhesion even with vibration and temperature changes. Once cured, the foam resists moisture, chemicals, and mold growth, ensuring long-term protection for your network infrastructure.
