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.
NOTE!
Before application, preliminary tests should be carried out with original materials under the respective conditions.
