3M 7100001804 Polyurethane Sealant 540 Black 10.5 Oz

Product Description

The 3M 7100001804 is a one-component, moisture-curing polyurethane sealant that forms permanently elastic bonds upon cure. Sold in a 10.5 fluid ounce cartridge, this black-colored sealant is designed for professional sealing and bonding applications across a wide range of substrates. The moisture-cure chemistry means no mixing is required — the product cures on exposure to ambient humidity. It is well-suited for trade professionals in construction, HVAC panel fabrication, glazing, and general industrial assembly who need a durable, flexible seal that resists movement and vibration after cure.

This sealant is used in both residential and commercial applications where a permanent, flexible bond is required between dissimilar materials. Typical install scenarios include sealing joints, seams, and penetrations in sheet metal assemblies, fiberglass reinforced panels, and structural components. It is appropriate for interior and exterior use where long-term elasticity and adhesion to mixed substrates are priorities.

Key Features

• One-component formula — no mixing required, cures with ambient moisture
• Forms permanently elastic bonds that accommodate joint movement and vibration
• Adheres to plastics, FRP, SMC, aluminum, steel, coated metal, and wood
• Black color for applications where a dark finish is required
• Standard 10.5 fluid ounce cartridge fits commonly available caulk guns

Compatibility

Designed for bonding and sealing applications involving plastics, fiberglass reinforced panels (FRP), sheet molding compound (SMC), aluminum, steel, coated metals, and wood substrates.

Installation Notes

Application is performed using a standard cartridge-style caulk gun. Surfaces should be clean, dry, and free of oil, grease, or loose material before applying sealant. Follow applicable building or mechanical codes for joint sealant requirements in your jurisdiction. Allow adequate cure time based on ambient temperature and humidity before subjecting the joint to stress or movement.
