Gunfoam NBS
Product description
Zettex Gunfoam NBS (PUR foam) is a durable, rapid-curing, one-component insulation and mounting foam developed for sealing and filling joints, seams and connections between cementitious building components. The foam hardens under the influence of moisture from the air and from the substrate. Polyurethane foam forms an excellent bond with most building materials such as stone, concrete, metal and various plastics (styropor, hard PU foam, polyester, hard PVC).
Material
Polyurethane.

Green
Applications
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.
