Bostik 940 Fast Set Black Marine SMP Adhesive Sealant

Description

Bostik 940 Fast Set Marine Adhesive Sealant is a black one-component SMP adhesive sealant for marine bonding and sealing above or below the waterline. Bostik 940 FS cures with moisture, skins quickly, and gives shops a flexible sealant choice for porous and nonporous materials.

Bostik 940 FS Benefits

• SMP chemistry gives a flexible bond and seal without isocyanates or solvent in the published product data.
• Fast skinning supports marine repair and production jobs where the surface must move to the next step sooner.
• UV resistance helps exposed seams hold color and appearance in outdoor service.
• Sandable and paintable finish supports finishing work after cure.
• Primer-free adhesion on many porous and nonporous surfaces can reduce prep steps after testing.

This sealant fits boat yards, transportation builders, sign shops, and maintenance crews that need elastic bonding on surfaces such as glass, PVC, wood, aluminum, steel, brass, fiberglass, and painted parts. Use it where a rigid adhesive would not handle movement, vibration, or weather exposure.

Where Bostik 940 FS Fits

• Marine deck, hatch, trim, and hardware sealing.
• Elastic bonding on aluminum, steel, fiberglass, and painted panels.
• Shop repairs that need a black sealant with a fast skin.
• Transportation and specialty vehicle seams exposed to weather.
• General manufacturing assemblies that need a paintable SMP seal.

Surface Preparation And Use

Bond surfaces should be clean, dry, and free of wax, oil, loose paint, and release agents. Test adhesion on the actual substrate stack before production, especially on plastics, coatings, and weathered surfaces. Tool the bead while it is fresh and protect the joint from movement until the material has enough strength for handling.

Follow the current SDS and TDS for ventilation, storage, application temperature, and cure timing. For related products, browse Chemical Concepts MS hybrid adhesives.
