U-Seal 208 BTR

Ultra-high viscosity for Bus, Truck & Rail industry one-part polyurethane direct glazing & structural bonding adhesive

U-Seal 208 BTR is a high viscosity, high decking and green strength one-component, flexible and high-performance polyurethane adhesive for commercial vehicles and bus, truck and rail glass direct glazing and general assembly. Highly resistant to UV radiation, weathering and ageing. Application fields Specifically addressed to the glass replacing and installation of front, side and rear windshields in the sector of Bus, Truck, Railway and industrial vehicles. Thanks to its high viscosity it guarantees a very high initial tack and is suitable for the application of large surfaces glasses typical in the BTR. Suitable for elastic structural bonding (assembly of various materials which are subjected to high thermal and dynamic stress) in the transportation Industry. The product is also characterized by a very high UV resistance and color stability making the product ideal for the sealing of exposed joints, including joints between lateral glasses. Once cured it provides an excellent semi-matt appearance for aesthetical purposes. Drive-away time (DAT) information
