3M 7000000861 Scotch-weld Epoxy Adhesive 2216 1 Qt Kit

Product Description

The 3M 7000000861 is a flexible, two-part epoxy adhesive sold as a 1-quart kit containing equal volumes of Part B and Part A. It uses a 1:1 mix ratio and delivers a work life of 120 minutes, with handling strength reached in approximately 10 hours at room temperature. No heat cure is required. Once fully cured, the adhesive provides high-strength bonds with strong performance in both shear and peel loading. It is well suited for bonding dissimilar substrates and for applications where some joint flexibility is required. Installers and maintenance technicians across industrial, mechanical, and commercial trades rely on this formulation where rigid adhesives would crack or delaminate under stress.

This adhesive is used in a wide range of applications including bonding rubber gaskets to metal housings, attaching plastic components to wood or metal panels, and securing assemblies that experience vibration or thermal cycling. It is appropriate for both shop fabrication and field repair work. The translucent cure color keeps bondlines unobtrusive on finished assemblies. It offers good environmental resistance, making it suitable for installations exposed to moisture, mild chemicals, or temperature variation.

Key Features

• Flexible two-part epoxy formulation resists cracking under shear and peel stress
• 1:1 mix ratio simplifies metering and reduces mix errors
• 120-minute work life allows time for fixture adjustment on large or complex assemblies
• Room-temperature cure — no oven or heat equipment required
• Bonds rubber, metal, wood, most plastics, and masonry substrates
• Translucent cure color keeps bondlines visually clean on finished parts
• Good environmental resistance for moisture- and chemical-exposed joints

Compatibility

Designed for bonding rubber, metal, wood, most plastics, and masonry products. Verify substrate compatibility and surface preparation requirements before use on production or critical structural joints.

Installation Notes

Surface preparation is critical — clean, degrease, and abrade substrates before application to achieve full bond strength. Dispense and mix Part B and Part A thoroughly at the 1:1 ratio before applying to the joint. Do not exceed the 120-minute work life window after mixing. Allow adequate cure time before loading the joint; full strength develops after room-temperature cure is complete.
