Multi-purpose sealant for marine applications

 Sikaflex-5911 is a sealant based on Sika's Silane Terminated Polymer (STP) technology. With its excellent resistance to harsh marine weather conditions it can be used for a wide range of applications. Sikaflex-591 exceeds common environmental and safety standards, and sets a new ecological benchmark. Sikaflex-591 meets the low flame spread standards (FTP code, part 5) established by the International Maritime Organization (IMO). 

Benefits:

• IMO approved
• Exceeds EH&S standards
• Free of isocyanates, solvents, PVC, phthalates and tin catalysts
• High elasticity
• Excellent stability to atmospheric agents
• Excellent workability and trowel characteristics
• It adheres well to a wide variety of substrates used in the marine industry

Uses:

 Sikaflex-591 is a multipurpose sealant designed for marine applications. It is suitable for elastic and vibration resistant bonding, and for a wide range of interior and exterior sealing applications. Sikaflex-591 adheres well to substrates commonly used in the shipbuilding industry. Sikaflex-591 is not suitable for applications with Teak wood and plastics which are prone to stress cracking (e.g. PMMA, PC, etc.). This product is suitable for experienced professional users only. To ensure adhesion and material compatibility, it is necessary to perform tests with the substrates under real conditions.li.

Surface preparation:

Surfaces must be clean, dry and free from grease, oil and dust.

The surface treatment depends on the specific nature of the substrates and is essential for a lasting bond. Suggestions for surface preparation can be found in the current edition of the appropriate Sika Pre-treatment Table. It must be considered that these suggestions are based on experience and must in any case be verified with tests on original media..

Application:

Sikaflex-591 can be processed between 5 C and 40 C, but variations in reactivity and application properties must be considered. The optimum temperature for substrates and sealant is between 15 C and 25 C. Sikaflex-591 can be processed with piston, manual, pneumatic or electric extrusion guns.riche.

In the event that Sikaflex-591 may come into contact with a polyurethane make sure that these products have hardened or wait at least 24 hours before sealing..
