"HYPERSEAL®-25LM-S" POLYURETHANE MASTIC FOR SEALING EXPANSION CONTRACTION JOINTS

Request a quote

HYPERSEAL.-25LM-S is a novel low modulus expansion joint sealant, especially formulated to contain both PU and silylated-PU technology, thus giving rise to a sealant which includes the best of both technologies. It has been modified in order to give enhanced thixotropic properties. It cures by reaction with atmospheric humidity to produce a joint sealant with a 50% joint movement accommodation factor and excellent adhesion on substrates traditionally problematic for PU sealants, e.g. glass, aluminum, steel, polycarbonate, etc. Additionally, the gunnable sealant has been modified in order to have extrusion profile identical to hybrid PU or MS technology. The extrusion rate and tooling of the sealant remain the same throughout a very wide range of temperature and humidity conditions.

Recommended For

  • Sealing joints in insitu concrete
  • Sealant for joints in expansion concrete plates
  • Sealing joints in precast panels
  • Adhesive for brick and block work
  • Sealings joints in water tanks and swimming pools
  • Sealant fot metal frames
  • Sealant for aluminum windows and panels
  • Joint sealant for irrigation channels

Advantages

  • Excellent adhesion on almost any type of surface, with or without the use of special primers
  • Excellent extrusion, tooling and storage stability over wide range of climatic conditions
  • Excellent chemical resistance, suitable for sealing joints in swimming pools and chemically treated water
  • Low modulus, joint movement accommodation 50%
  • Microorganism and fungus resistant
  • Application under water immersion possible
  • Excellent heat resistance, suitable for application where exposure to temperatures >60°C take place
  • Resistance to cold: the sealant remains elastic even down to -40 oC o.
