Merbenature – Ecological SMP Sealant

Merbenature is an ecological and environmentally friendly SMP sealant adhesive since it is formulated with renewable raw materials.

Features of Merbenature

  • It is easy to use, elastic and moisture cures.
  • It meets the application requirements of ISO 11600 F25-LM.
  • It can be labelled with the “DIN” certification symbol for bio-based products.
  • Based on the new merbenTECH technology.
  • It belongs to the class of silane-modified polymers made through the functionalisation of polymer chains with silane components and is known as SMP.
  • SMPs combine the properties of two sealing systems: polyurethane and silicone. It is possible to obtain flexible formulations typical of polyurethanes, such as compatibility with paints and the high elasticity of silicones.
  • Very low in emissions (complying with EMICODE EC1 + R ).
  • It does not contain halogens, phthalate softeners, isocyanates, solvents or tin catalysts.
  • It is the world’s first eco-friendly sealant that is “50-85% bio-based”.


  • Renewable and elastic
  • Sustainable
  • Solvent-free
  • Neutral odour


  • Its main application is the sealing of moving joints and connection elements in building construction, as well as connection joints in concrete, brick, plaster, wood, various metals and plastics in interior and exterior areas.
  • It is suitable for interiors where people stay, such as public buildings, homes, kindergartens, and schools.
  • Compatible with plastically hardened paints, varnishes and mortars, the sealant can certainly be compared to traditional commercially available products.
