Gun Foam NBS
Zettex Gunfoam NBS is a durable and fast-curing one-component insulation and mounting foam. Developed for sealing and filling joints and connecting building materials. The foam cures under the influence of moisture. Zettex Gunfoam NBS has excellent adhesion to most building materials such as stone, concrete, metal and various plastics (styrene, PU rigid foam, polyester, rigid PVC)
Material

Color
Green
Sealing joints between partition walls, ceilings, and floors.
Penetrations of pipes and conduits through walls and floors. Joints around door and window frames. Not suitable for underwater applications and not to be used to fill large closed spaces. For wider joints and joints deeper than 5 cm, apply the foam in several layers. Wait 15-30 minutes between layers.
Surface
All surfaces must be free of dust and grease.
