3M 7100046020 Scotch-weld Epoxy Adhesive 100 Plus Clear 5 Gal

Product Description

The 3M 7100046020 is Part A of the Scotch-Weld Epoxy Adhesive 100 Plus system, a clear, colorless, two-part structural adhesive formulated for flexible, fast-setting bonds at room temperature. It uses a 1:1 mix ratio and delivers a 3 to 5 minute work life, reaching handling strength in approximately 20 minutes without the need for elevated heat or UV curing. Its low viscosity makes it easy to pour and well-suited to filleting and potting applications. Licensed contractors, assembly technicians, and industrial maintenance professionals rely on this adhesive where a tough, flexible bond line is required across dissimilar substrates.

This product is used in residential, commercial, and light industrial settings wherever a fast-curing, flexible epoxy bond is needed. It bonds metals, ceramics, wood, and many plastics, making it a practical choice for fabrication, repair, and potting work. The 5-gallon container size is suited for high-volume production environments or job sites with sustained adhesive demand. The room-temperature cure eliminates the need for ovens or heat lamps, simplifying the workflow on most installations.
