Description
Specifications
Zettex Gunfoam NBS is a fast-curing, one-component polyurethane assembly foam designed for sealing and insulating gaps, joints and penetrations in construction elements. The foam cures under the influence of moisture and offers excellent adhesion to most commonly used building materials, including stone, concrete, metal and various plastics.
Formulated for high durability and insulation performance, the foam provides a dense, stable structure suitable for a wide range of indoor and outdoor applications. The product is manufactured without CFC or HCFC propellants, supporting environmentally responsible use.
Typical applications include sealing gaps between walls, ceilings and floors, insulating pipe and cable penetrations, and sealing around window and door frames. The foam is not intended for underwater use or filling large closed cavities.
