SILRES® BS SMK 550 is a solventless silicone microemulsion concentrate based on silanes and siloxanes that is diluted with water to yield microemulsions. Such dilute aqueous solutions serve as chemical damp-proofing agents. The WTA has certified the suitability of SILRES® BS SMK 550 for this application.


  • solventless silicone microemulsion concentrate
  • dilutable simply by pouring into drinking water
  • ready-to-use silicone microemulsions which have been activated with water must be used up on the day of dilution

Advantages over ready-to-use products:

  • lower packaging costs
  • fewer problems with empty containers
  • disposal (15 times less packaging)
  • lower storage and transport costs
