Merbenit SF50 is a reactive flexible adhesive based on SMP (Silane Modified Polymer). SMP based adhesives combine all the advantages of silicones with  polyurethane strengths and are free of solvents, isocyanates and silicones. Merbenit SF50 is odourless and does not contain hazardous components (check Safety Data Sheet).

Thanks to its fast strength build-up and high tensile strength, Merbenit SF50 is ideal as adhesive for various materials and surfaces.

Merbenit SF50 features

After application, Merbenit SF50 adhesive has a high Green strength, allowing quick fix. When fully cured has high tensile strength (3 N/mm2).  Neutral curing and compatible with paints.

  • Free of solvents, isocyanates and silicones.
  • Fast strength build-up
