Bostik 920 Fast Set Black Marine Urethane Sealant Adhesive

Description

920 Fast Set sealant is a black Bostik urethane adhesive and sealant for marine, transportation, and industrial assembly work. The product context describes a faster-setting version of Bostik 920 for sealing and bonding hatches, windows, doors, cleats, windshields, FRP panels, aluminum, metal, wood, and many plastics. It gives crews a tough flexible bead where a slower marine urethane would slow return-to-service timing.

920 Fast Set sealant Applications

• Sealing marine hatches, deck hardware, windows, and doors.
• Bonding fiberglass, FRP, aluminum, metal, wood, and selected plastics after fit testing.
• Installing windshields, cleats, sunroofs, and trim where a black bead is specified.
• Transportation, sign, and fabrication work that needs a flexible urethane joint.
• Repair work where faster tack-free timing helps crews move parts sooner.

The original product copy notes that Bostik 920 gives up to six hours of repositionability, while the Fast Set version dries tack-free much sooner. Use the current Bostik data sheet to confirm skin time, cure rate, temperature limits, and substrate preparation before approving a production process.

920 Fast Set sealant Benefits

• One-component urethane format avoids mixing and metering at the bench.
• Flexible cured joint helps handle vibration and movement in marine and vehicle assemblies.
• Good fit for above-water and below-waterline sealing when the application is qualified.
• Black color supports visible trim, hardware, and gasket-style bead lines.
• Cartridge packaging fits standard manual and pneumatic dispensing tools.

Surface Preparation and Use

Clean, dry, and decontaminate the bond area before applying material. Remove loose paint, oil, wax, release agents, and sanding dust. Mask visible edges when bead appearance matters, then tool the sealant before skin forms. Allow the joint to cure according to the current technical data sheet before loading, immersion, or service exposure.
