Bonding and sealing of external parts and interior rail vehicles

a) Structural adhesives for roof, floor and body parts and other components to be bond

Compared to welded and mechanical bonds the structural and semi-structural adhesives from the product portfolio offered by Bodo Möller Chemie South Africa optimize life, structural integrity as well as acoustic management in rail vehicle construction. Applications include doors, hood, lid hinges, engine compartment, instrument panels, roof trusses, longitudinal beams and other supporting components of rail vehicles.

Benefits at a glance:

  • Bonding of various materials
  • Ability of expansion and contraction of gaps
  • To improve the rigidity of the body
  • Reduction of vehicle weight
  • Streamlined production
  • Reduced production time

b) Sealing systems for sealing joints, for filling joints and underbody protection

With Bodo Möller Chemie South Africa you will find quality products for sealing, filling and bonding lightweight materials in rail vehicles. As body seams are sealed, they offer more protection against corrosion and hold dust, dirt and moisture from the inside of the vehicle. They also provide better adhesion, acoustics and thermals.

Benefits at a glance:

  • Prevention of rails noise and external noise
  • Automatic application, coatable
  • Permanent elasticity

Application

  • Inner lining seams, seam sealing for glass roofs, visual enhancement of visible seams inside and outside
  • Gap filling between trim panels, panels for insulation of impacts and vibrations
  • Sealing of aluminum components, lightweight materials, frames of wood, metal and plastic or window frames
  • Sealing bulkhead and fixation of door panels, mudguards and wheel arches
