3M 7000046345 Metal Sealant Aluminum 55 Gallon

Product Description

The 3M 7000046345 is a one-part, aluminum-colored, general purpose metal sealant designed for industrial and trade applications. It air-dries to a tough, flexible film that resists water, oils, and fuel, making it suitable for sealing and bedding tasks in demanding environments. The medium viscosity formula spreads easily and adheres well to aluminum, other metals, and wood surfaces. This sealant is typically applied by maintenance technicians, glaziers, and general contractors working on metal fabrication, fenestration, or building envelope projects. It is supplied in a 55-gallon drum with a poly liner for bulk dispensing operations.

This sealant is well suited for bedding glass in aluminum window channels, sealing metal joints and seams, and general-purpose bonding tasks across residential and commercial construction and maintenance settings. Its flexible cure makes it appropriate for applications where surfaces experience thermal expansion or minor movement. The aluminum color allows it to blend with standard aluminum framing and metal panel systems commonly found in commercial glazing and curtainwall installations.

Key Features

• One-part formula — no mixing required, ready to apply from the container
• Air-dries to a tough, flexible film bond
• Resists water, oils, and fuel after cure

Compatibility

Designed for use on aluminum window channels, general metal substrates, and wood surfaces where a flexible, aluminum-colored sealant is required.

Installation Notes

Application should be performed by qualified tradespeople familiar with sealant and glazing work. Surfaces must be clean, dry, and free of grease, loose scale, and contaminants before application. Follow all applicable building code requirements and manufacturer safety data sheet guidance when handling bulk sealant containers. Avoid applying to surfaces that will be submerged continuously or exposed to conditions outside the product-rated resistance range.
