Product details

1-component sealant based on Sika's silane-terminated polymer (STP) technology. Sikaflex 591 was specially developed for the harsh marine conditions outdoors and is therefore extremely weather-resistant. Also suitable for indoor applications.
With sealant 591, Sika sets new environmental standards concerning the user's safety and health: the sealant is free of tin, phthalates, isocyanate, solvents and PVC, and thus exhibits the lowest emissions of all available sealants for maritime applications. In addition, Sikaflex 591 has a long color stability and can easily be painted over with the common marine paint systems.

Application areas
  • Outdoor and indoor sealing applications
  • Broad adhesion spectrum
  • Creating elastic and vibration-damping sealing joints

Once again a first-class product from the SIkaflex series. Easy to work with, sticks and seals.

elasticity retained
The shroud penetrations of our boat built in 1982 are a permanent construction site... The sealant keeps the 'inflow' within limits for a few years.
