Employments

Sikaflex-291i is a multipurpose product used in shipbuilding. It is suitable for making elastic and vibration resistant seals, and can also be used for a variety of internal seals..
Sikaflex-291i adheres very well to materials commonly used in marine construction, such as wood, metals, metal primers and paint systems (two-component systems), ceramic and plastic materials (fiberglass, etc.). Sikaflex-291i must not be used for sealing on plastic materials subject to stress cracking phenomena (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.

Surface preparation

Surfaces must be clean, dry and free of any traces of 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-291i can be processed between 10 C and 40 C but variations in reactivity and application properties must be considered. The optimum temperature for substrates and sealant is between 15C and 25C.5 °C.
Sikaflex-291i can be processed with manual, pneumatic or electric piston guns..

Spatolatura and finishing

Tooling and finishing must be done within the skin formation time of the sealant.

The use of Sika Tooling Agent N is recommended. Other finishing agents should be tested for suitability and compatibility prior to use..

Removal

Uncured Sikaflex-291i can be removed from tools and equipment with Sika Remover-208 or another suitable solvent. Once hardened, the material can only be removed mechanically. Hands and exposed skin should be washed immediately using hand cleaning wipes such as Sika Cleaner-350H, or a suitable industrial hand cleaner and water.ua.

Do not use solvents on the skin!

Overpainting

Sikaflex-291i can be optimally painted after skin formation. The paint could be improved by treating the joint surface with Sika Aktivator-100 or Sika Aktivator-205 prior to the paint process. If the paint requires a firing process (> 80 C), the best performance is achieved by allowing the sealant to fully cure sooner. All paints must be tested by carrying out preliminary tests under the same production conditions. The elasticity of paints is usually lower than that of sealants. This could lead to paint cracking in the joint area.one.
