Sika 291 multipurpose sealant 

DESCRIPTION

Sikaflex 291 is a special one-component Polyurethane sealant, specifically designed for applications in the shipbuilding industry. This sealant cures upon exposure to atmospheric moisture, forming an elastic and durable elastomer. The product meets the standards of the International Maritime Organization and is manufactured under the ISO 9001/14001 quality assurance system.

APPLICATIONS

Sikaflex 291 has diverse applications and is suitable for shipbuilding technology. It is used to create elastic, vibration-damping joints and to seal internal and external seams. The product bonds well with materials commonly used in the shipbuilding industry such as wood, metals, various metal primers and topcoats (two-component), ceramic materials, and plastics. However, Sikaflex 291 should not be used with brittle materials such as glass, plexiglass, and polycarbonate. After curing, the product can be sanded to achieve the desired finished surface.

ADVANTAGES

Sikaflex 291 has many notable advantages:

One-component: Easy to use without needing to combine multiple components.

Elastic: Creates an elastic elastomer layer, helping to resist breakage and vibration.

Non-aging and weather-resistant: Designed to withstand outdoor environments and not age over time.

Good adhesion to most substrates: The product bonds strongly with many common materials in the shipbuilding industry.

Paintable: Can be painted after the product has cured, helping to achieve a better finished surface.

Non-conductive: Safe for applications requiring electrical insulation.

Low odor: Reduces impact on the environment and users.
