A Guide to Merbenit E20 Lightweight SMP Adhesive & Sealant

Table of Contents

Less weight means less energy consumption and less pollutant emission. This leads to environmental compatibility and to more sustainability.

Merbenit E20 is as powerful as conventional elastic adhesive and sealing material, with only half its weight: Save more than one kilogram per sealed square metre.

With a density of 0.7 g/cm³ Merbenit E20 is much lighter than other products. This permanent elastic adhesive and sealant based on SMP is suitable for many industry and automotive applications. Other special features are the noise insulating and vibration damping properties.

Product advantages of Merbenit E20

  • 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

Application of Merbenit E20

Absorbation of vibrating elements, isolation of voids and noise, heat and cold insulation in vehicle constructions. Car body sealings and weakly stressed or large area bonding in the car interior.

Application: Industry, Automotive, Marine

Substrate range of Merbenit E20

Suitable materials are metals, powder-coated, varnished, galvanised, anodised, chromed or hot zinc dipped surfaces, various plastics, ceramics, stone, concrete and wood. Due to the large variety of different plastics and compositions as well as materials which are susceptible cracks, preliminary tests are recommended.
