Structural Bonding • Marine Adhesive Sikaflex®-292 Marine Adhesive SealantSikaflex®-292 is a high-performance, 1-component, moisture-cured polyurethane adhesive specifically engineered for the marine industry. Its thixotropic, paste-like consistency means it will not sag, making it highly effective for vertical and overhead application. Once cured, it exhibits excellent mechanical strength and gap-filling properties, making it the go-to choice for structural joints subjected to high dynamic stresses. |

Key Product Benefits
- Multi-Purpose Structural Bonding: Built to withstand high dynamic stresses in harsh marine environments.
- Excellent Gap-Filling: Accommodates uneven bond lines effortlessly.
- Paintable: Can be over-painted once cured for a seamless finish.
- Versatile Adhesion: Bonds securely to aluminum (and anodized finishes), metal primers, 2-part coatings, ceramics, and plastics like GRP and ABS.
- Easy Processing: 1-component moisture-curing system requires no mixing.
Common Marine Applications
- Structural bonding in boat building and marine repairs
- Bonding aluminum and coated metals
- Bonding fiberglass (GRP) and composite hull components
- Deck-to-hull joints and hardware installation requiring a serviceable bond
- Bonding engineering plastics including ABS
