Sealing systems for sealing and filling of joints and underbody protection car, automotive

With us you will find quality products for sealing, filling and bonding lightweight materials in cars and  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:

  • Road noise and engine noise absorbing
  • Recoatable for an optimal finish
  • Reduction of vehicle weight
  • Permanent elasticity


  • 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

In some cases, cleaners and primers are needed, in others sealant or adhesive can be applied without primer directly onto substrates.

Expanding sealants for sealing of cavities and Acoustic dampening
The expanding sealants from L&L Products are placed before the KTL process (cataphoretic dip painting) in the body. During the KTL-drying process, our thermally activated sealants expand, fill the cavity and seal it off completely. Our product range of expanding sealants consists of rubber-based and EVA-based materials, which, after activation and linking fill different volumes, with different density and cell structures.
