Soudal Genius Gun Gap Filling Expanding Foam 500ml

Soudal Genius Gun Gap Filling Expanding Foam in a 500ml aerosol can is a one-component, self-expanding polyurethane foam formulated for high filling capacity and precision application. The product incorporates the patented Genius Gun system - an integrated, reusable adaptor for controlled dosing and enhanced handling comfort. This expanding foam delivers a stable, thixotropic consistency that cures by moisture to form a dense, elastic structure with minimal shrinkage or post-expansion. It adheres firmly to most construction materials, including masonry, concrete, wood, and metal, excluding polyethylene (PE), polypropylene (PP), and polytetrafluoroethylene (PTFE). With a cured density of approximately 25 kg/m³, the foam provides robust thermal and acoustic insulation, achieving a sound reduction value of 58 dB and a thermal conductivity of 37 mW/m·K. Once fully cured, it withstands temperatures from –40 °C to +90 °C, or up to +120 °C for short exposure. Soudal Genius Gun Gap Filling Expanding Foam 500ml is ideal for controlled cavity filling, sealing, and bonding where a stable, elastic joint is required. Its precise application ensures clean, professional results in static and non-static installations.
