Sikaflex 291i Adhesive And Sealant 300ml

Sikaflex 291i adhesive and sealant 300ml is a non‑sag, 1‑component polyurethane sealant specifically developed for the marine market. This sikaflex 291i adhesive and sealant 300ml cures on exposure to atmospheric moisture to form a durable, elastic joint that resists movement and maintains adhesion in demanding marine environments. The formulation meets the low spread of flame requirements set out by the International Maritime Organisation (IMO), making it suitable for applications where fire performance is a consideration.

Designed for professional marine use, Sikaflex‑291i offers reliable bonding to a wide variety of substrates commonly found on vessels, including metals, composites and many plastics. Its low odour and non‑corrosive chemistry improve on‑board comfort and compatibility with sensitive materials. The product’s low isocyanate content and very low VOC profile support safer handling and reduced environmental impact compared with older polyurethane systems. Sikaflex‑291i is also paintable, allowing finished joints to be overcoated for aesthetic or protective reasons.

Typical marine applications include sealing and bonding in superstructures, deck fittings, hatches, windows and other interfaces where a flexible, long‑lasting seal is required. The non‑sag characteristic ensures neat tooling and vertical application without slump, while the single‑component format simplifies storage and on‑site use.
