3M 7100198009 Polyurethane Sealant 540 600ml Black

Product Description

The 3M 7100198009 is a single-component, moisture-curing polyurethane adhesive sealant sold in a 600 mL sausage pack. It forms flexible, elastomeric bonds that seal against weather, vibration, and joint movement. Rated for service from -40 degrees F to 194 degrees F, this sealant bonds dissimilar substrates including plastics, fiberglass reinforced plastic (FRP), sheet molding compound (SMC), aluminum, steel, coated metal, and wood. High tensile strength combined with low hardness allows the cured bead to absorb shock and accommodate long-term joint movement without cracking. Licensed tradespeople in construction, transportation manufacturing, and industrial fabrication rely on this product for exterior panel bonding, storefront glazing, and structural sealing applications.

This sealant is suited for both residential and commercial projects where a durable, weather-resistant bond between dissimilar materials is required. Typical applications include exterior facade panel bonding, retail storefront assembly, transportation vehicle manufacturing, and industrial enclosure sealing. The black color makes it appropriate for visible joints where a dark finish is specified. The sausage pack format is designed for use with compatible bulk dispensing guns, which speeds production in high-volume assembly environments.

Key Features

• Single-component formula requires no mixing and simplifies application
• Bonds dissimilar materials: plastics, FRP, SMC, aluminum, steel, coated metal, and wood
• Maintains elasticity after cure for shock absorption and long-term joint movement
• Skin-over time of 60 to 90 minutes allows painting once fully cured
• Weather-resistant performance from -40 degrees F to 194 degrees F
• 600 mL sausage pack format compatible with bulk dispensing equipment

Compatibility

Designed for bonding and sealing applications involving dissimilar substrates including plastics, FRP, SMC, aluminum, steel, coated metal, and wood in industrial, transportation, and construction settings.

Installation Notes

Surface preparation is critical — clean and dry all substrates before application and remove any loose material, oils, or coatings that may inhibit adhesion. Dispense using a compatible sausage-pack bulk gun and tool the bead before the sealant begins to skin. Do not apply to wet surfaces or in ambient conditions outside the rated temperature range. Allow full cure before exposing the joint to service loads or weather.
