Bostik Fireban One
Bostik Fireban One
Bostik Fireban One is a single component, fire rated, low modulus polyurethane sealant curing via air humidity or moisture to form a elastomeric weatherproof fire rated and acoustic seal. Fireban One is a Class A polyurethane sealant. When cured it will form a tough, flexible seal capable of cyclic expansion and compression movement of 50% (25%) of the original joint width. Fireban One is virtually unaffected by normal weathering conditions such as rain, sunlight, snow, sleet, ultra violet radiation, ozone, atmospheric contamination and pollution.
