Description
Bostik FIREBAN ONE is a one-component, low-modulus, intumescent polyurethane sealant designed for construction joints and service penetrations requiring fire resistance and accommodation of movement. It cures into a tough, flexible seal capable of repeated expansion and compression, with movement capability of ±25% of the original joint width. Suitable for fire-rated and acoustic sealing applications, it provides adhesion to a range of building materials and resistance to normal weathering conditions. Its gun-grade consistency allows smooth application and tooling, while its paintable, non-staining finish supports a neat appearance. Fire resistance of up to four hours is achievable in suitable tested joint and penetration configurations.
