Sikaflex 291i Adhesive/Sealant 300ml
- Color: navy black
- Size: 300ml, cartridge
- Benefits/features:
- Recommended primarily for locations above the waterline
- 1-component
- Elastic
- Mild scent
- Weather and aging resistant
- Does not cause corrosion
- Can be overpainted with many different types of paint
- Sandable
- Reliably glues and seals various material surfaces
- Acts as an electrical insulator.
Sikaflex 291 black is an excellent general purpose sealant. A versatile and flexible marine sealant that bonds all standard materials used in boat building. Its superior flexibility ensures a durable and long-lasting seal, similar to other Sikaflex Marine sealants and adhesives. Sikaflex 291 is a single-component, easy-to-use and highly elastomeric product.
Note! For underwater sealing, it is recommended to use Sikaflex 591 sealant or Sikaflex 292i adhesive .
Use: The product is suitable for sealing various movement joints as an elastic and vibration-absorbing material and for numerous sealing applications. The product reliably bonds and seals materials used in the boat and shipbuilding industry. The product is suitable for wood, metal, metal primer and paint surfaces (2-K), ceramics and certain plastics (e.g. fiberglass, etc.).
PRODUCT BENEFITS
- Helm marked
- 1-component
- Very elastic
- Mild scent
- Does not cause corrosion
- Limited overpaintability
- Adheres well to most material surfaces for marine use
- Does not contain solvents
- Very low VOC
- Low isocyanate content
APPLICATIONS
SIKAFLEX 291i black is a multi-purpose product for marine applications. The product is suitable for elastic and vibration-damping sealing of joints and for use in numerous interior sealing applications. Sikaflex 291i adheres particularly well to material surfaces commonly used in marine structures, such as wood, metals, metal primers and paint surfaces (2-K systems), ceramic materials and plastics (reinforced plastic, etc.). Sikaflex 291i is not suitable for sealing plastic types sensitive to stress cracking (e.g. acrylic and polycarbonate plastics, etc.). The product should be tested on actual material surfaces and under operating conditions to ensure adhesion and compatibility properties.
CURING METHOD / DRYING TIME
Sikaflex 291i black dries through due to the influence of air humidity. At low temperatures, air humidity decreases, causing the adhesive to dry through more slowly.
CHEMICAL RESISTANCE
Sikaflex 291i is generally resistant to water, seawater, diluted acid and diluted alkali solutions. It is temporarily resistant to fuels, mineral oils, vegetable and animal fats and oils. It is not resistant to organic acids, glycol alcohols, concentrated mineral acids and alkaline solutions or solvents.
USING THE PRODUCT
Surface preparation
Surfaces must be clean, dry and free from grease, oil and dust. The use of adhesion promoters significantly improves the long-term adhesion of the compound. Material surface-specific suggestions for adhesion promoters can be found in the current Sika Pre-treatment Chart for the product range. The suggestions are based on our experience but must always be confirmed by carrying out adhesion tests on real material surfaces to ensure long-term adhesion.
INTENDED USE
Sikaflex 291i can be applied in the temperature range of 10 °C - 40 °C, taking into account changes in drying speed and application properties. Optimal application conditions are achieved when the material surface and mass temperature are between 15 °C and 25 °C. It is recommended to use a piston-operated gun (manual, pneumatic or battery-operated) to dispense the Sikaflex 291i cartridge.
Seam finishing
The joint must be finished within the open time specified for the product. The recommended finishing agent is Sika® Tooling Agent N. The user must check/ensure the suitability/compatibility of other finishing agents before use.
Stain removal
Uncured Sikaflex 291i can be removed from tools and equipment with Sika® Remover-208 or another suitable solvent. Once dried, the product can only be removed mechanically. Hands and other contaminated skin should be cleaned immediately with Sika® Cleaner-350H or a suitable industrial detergent and water (no solvents).
Overpainting
Sikaflex 291i is best overcoated after the skinning period. Paint adhesion can be improved by wiping the joint surface with Sika® Aktivator-100 or Sika® Aktivator-205 before painting. If the paint requires baking (> 80 °C), the best result is achieved when the compound is allowed to dry thoroughly before overpainting. Overpainting tests should be carried out in advance on the customer's painting line for all types of paint intended for use. The elasticity of the dried paint film is usually lower than that of the sealant, which can lead to breakage of the paint film in the area of ??the expansion joint.
