Product Description
Polyurethane foam sealant is a single-component, moisture-curing, versatile polyurethane foam filling and elastic sealing material. Also known as Polyurethane (PU) Foam Filler, it is an essential auxiliary material in the door, window, and curtain wall industry. It fills polyurethane prepolymer, catalyst, and propellant into a pressure-resistant iron aerosol can. During construction, the foam is sprayed onto the intended construction site using a matching glue gun or manual spray nozzle, completing the forming, foaming, bonding, and sealing process in a short period.
