Merbenit E20 - Lightweight SMP Sealant

Merbenit E20 is a lightweight sealant based on SMP (Silane Modified Polymer) for construction and transportation industries.

Merbenit E20 has a density of 0.70 g/cm³, making it 50% lighter than other sealants.

The adhesive has sound insulation properties that absorb vibrations and low thermal conductivity, making it an excellent thermal insulator.


  • Very flexible and resilient, the adhesive can be used as a gasket compression.
  • The adhesive can be used to absorb vibrating elements, isolating voids and noise, heat and cold insulation in vehicle constructions.
  • Car body sealings and weakly stressed or large area bonding in car interiors.


  • Very low density
  • Low thermal conductivity
  • Noise insulating and vibration damping
  • Compressible
  • Simple processing
  • Tolerance compensating
  • Permanently elastic and stress compensating
  • Free of solvents, isocyanates and silicones
