Sikaflex®-591 is a multipurpose sealant based on Sika’s Silane Terminated Polymer (STP) technology. With its excellent resistance against the harsh maritime weathering conditions, it can be used for a wide range of marine applications.
The product exceeds common environmental and safety standards and sets a new benchmark from an ecological point of view; it meets the low spread flame requirements (FTP Code Part 5) set out by the International Maritime Organization (IMO).
AREAS OF APPLICATION
Sikaflex®-591 is suitable for elastic, vibration-resistant joint seals and for a wide variety of interior and exterior sealing applications, while it is not suitable for applications with teak wood and plastics that are prone to stress cracking (e.g. PMMA, PC, etc.). It bonds well to substrates commonly used in the marine industry.
This product can be used only by experienced professional users only. Test with actual substrates and conditions have to be performed to ensure adhesion and material compatibility.
CURE MECHANISM & CHEMICAL RESISTANCE
Sikaflex®-591 cures by reaction with atmospheric moisture. At low temperatures the water content of the air is generally lower and the curing reaction proceeds somewhat slower. The product is:
- generally resistant to fresh water, seawater, diluted acids and diluted caustic solutions;
- temporarily resistant to fuels, mineral oils, vegetable and animal fats and oils;
- not resistant to organic acids, glycolic alcohol, concentrated mineral acids and caustic solutions or solvents.
