Description
Flexible HVAC Duct Sealant for Metal Ductwork & Ventilation Systems
Soudaduct is an acrylic polymer-based HVAC duct sealant designed for creating airtight seals in metal ductwork and ventilation systems. Its plasto-elastic, solvent-free formulation provides excellent adhesion to galvanised steel, stainless steel and other common ducting materials while remaining permanently flexible after curing.
Developed specifically for HVAC applications, Soudaduct is suitable for sealing seams, flange joints, spigot joints and penetrations in ductwork systems. The low-odour formula can be applied by brush or sealant gun and can be painted once cured, making it ideal for both new installations and maintenance work.
Soudaduct conforms to Class C of DW144 and ISO 11600 Class 12.5P, making it suitable for professional HVAC sealing applications requiring reliable airtight performance.
