Description

Sikaflex 591 multipurpose black sealant for marine applications 300ml

Sikaflex®-591 is a sealant based on Sika’s Silane Terminated Polymer (STP) technology. With it’s excellent resistance against the harsh maritime weathering conditions it can be used for a wide range of applications.
Sikaflex®-591 exceeds common environmental and safety standards and sets a new benchmark
from an ecological point of view. Sikaflex®-591 meets the low spread flame requirements (FTP Code Part 5) set out by the International Maritime Organization (IMO).

Benefits
▪ IMO approved
▪ Exceeds EH&S standards
▪ Free of isocyanate, solvents, PVC, phthalates and tin catalysts
▪ Highly elastic
▪ Excellent weathering stability
▪ Very good processing and tooling characteristics
▪ Bonds well to a wide variety of marine substrates

Uses
Sikaflex®-591 is a multipurpose sealant designed for marine applications. It is suitable for elastic, vibration-resistant joint seals and for a wide variety of interior and exterior sealing applications.
Sikaflex®-591 bonds well to substrates commonly used in the marine industry. Sikaflex®-591 is not suitable for applications with teak wood and plastics that are prone to stress cracking (e.g. PMMA, PC, etc.).
This product is suitable for experienced professional users only. Test with actual substrates and conditions have to be performed to ensure adhesion and material compatibility.

METHODOF APPLICATION
Surface preparation
Surfaces must be clean, dry and free from grease, oil and dust.
Surface treatment depends on the specific nature of the substrates and is crucial for a long lasting bond. Suggestions for surface preparation may be found on the current edition of the appropriate Sika® Pre-treatment Chart. Consider that these suggestions are based on experience and have in any case to be verified by tests on original substrates.

Application
Sikaflex®-591 can be processed between 5 °C and 40 °C but changes in reactivity and application properties have to be considered. The optimum temperature for substrate and sealant is between 15 °C and 25 °C. Sikaflex®-591 can be processed with hand, pneumatic or electric driven piston guns.
In case Sikaflex®-591 could get in contact with polyurethane ensure that those products are cured or wait at least 24 hours prior to seal.

Tooling and finishing
Tooling and finishing must be carried out within the skin time of the product. It is recommended using Sika® Tooling Agent N. Other finishing agents must be tested for suitability and compatibility prior the use.

Removal
Uncured Sikaflex®-591 can be removed from tools and equipment with Sika® Remover-208 or another suitable solvent. Once cured, the material can only be removed mechanically. Hands and exposed skin have to be washed immediately using hand wipes such as Sika® Cleaner-350H or a suitable industrial hand cleaner and water. Do not use solvents on skin!
