ISPOFLEX 55/2 a one-component, high viscosity, flexible and high performance polyurethane adhesive that cures on exposure to atmospheric moisture to form a tough, durable adhesive. Completely solvent free it is odorless and also non-conductive allowing the correct bonding to glass incorporating radio antenna or additional electrical equipment. Highly resistant to UV irradiation, weathering and ageing.


  • One component polyurethane
  • Suitable for cold application
  • High viscosity – high initial tack and non sag properties
  • Short cut-off string
  • Suitable for use with integral aerials
  • Prevent contact corrosion in aluminum – body vehicles
  • High UV resistance and color stability


ISPOFLEX 55/2 is 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 good UV resistance and color stability making the product ideal for the sealing of exposed joints, including joints between lateral glasses. This once cured it provide an excellent semi-matt appearance for an esthetical purpose.
